[need testing] Krita HDR support on Wayland

dkazakov · October 30, 2025, 3:34pm

Hi, all!

I have just merged the Wayland HDR support into Krita Next (nightly)! If you happen to have an HDR-capable display and use Linux/Wayland and have a bit of time to test the new feature, I would be really appreaciate a little bit of help with testing.

The situation is actually a little bit complicated, since there are numerous implementations of the Wayland protocol. I have tested with KWin only, and it would be nice to test on other compositors as well.

Package (uses Qt6):

Linux: https://invent.kde.org/graphics/krita/-/jobs/3524281/artifacts/raw/_packaging/krita-6.0.0-prealpha-d5143427b6-x86_64.AppImage

How to run in Wayland mode:

QT_QPA_PLATFORM=wayland krita-*.AppImage

What changed (and should be tested):

The color management settings page has changed completely:

To get proper color management (and HDR) you need to check Enable canvas color management checkbox and make sure that Current canvas surface bit depth label says 10-bit. Please take it into account that the change of canvas’ bit-depth can requires Krita restart. It happens due to technical limitations of Qt.
After you made sure that Krita uses 10-bit mode, you can enable HDR in your window manager, e.g. in KWin. Krita should detect it instantly (without any restart).

Good HDR test images can be found here: GitHub - AcademySoftwareFoundation/openexr-images: Collection of images associated with the OpenEXR distribution
If you have multiple displays, one of which HDR, and the other not, then moving Krita’s window between the screens should enable/disable HDR.
[for SDR mode] Image->Image Properties->Softproofing page has been completely rewritten. Now there is no “Adaptation” slider. There is a checkbox instead. The user is left with either “full
adaptation” or “no adaptation”. Please take it into account that on Wayland this checkbox currently does nothing and Krita behaves as if it is always enabled (Wayland does not support “no adaptation” right now).

Otherwise, Softproofing dialog should work as before in SDR mode.

Note

If you happen to face any color-management problem on Wayland, you can check (and attach to the bug report) a special color management report from Help->Show color management information. It shows information about everything, canvas, your display and your compositor.

I have a m28u monitor which seems to be ok for HDR according to rtings review. I’m on arch linux and on Kwin/KDE. I’ve enabled HDR in my display settings for the m28u

I followed your steps and to enable 10bit mode:

On the openxr github are there any images you recommend to view? I’m not sure how to be able to “tell” HDR is enabled.

I did get a crash moving Krita between my m28u monitor and my non HDR monitor. I’m not sure if its related:

Hi, @Reinold!

On the openxr github are there any images you recommend to view?

StillLife.exr and Desk.exr are good examples.

I’m not sure how to be able to “tell” HDR is enabled

HDR is disabled on your system. ColorSpace->Luminance->maxLuminance value should be higher than referenceLuminance to count as HDR. And KWin usually enables st2084_pq transfer function in HDR mode.

What version of KWin you use?

UPD:

If you manage to produce a backtrace for this crash (even without debugging symbols), it would help a lot.

Tested this build with StillLife.exr and no dice. The image loads, but is extremely blown out and for some reason has an off-white background rather than the usual Krita grey. I tested with some SDR images for comparison and those were blown out too. The “display format” in HDR settings shows as 10 bits, although is grayed out and says 8 bits is the selected option.

I’m running an Alienware AW3423DWF monitor on Fedora 42 with a Radeon RX 7900 XTX GPU, and have been able to run other HDR applications fine. The colour management information is as follows:

Hi, @olderocean!

Please attach your Help->Show color management information report. Does the image actually look like HDR on your screen?

The screenshot of the settings page looks like HDR is actually enabled by the compositor

dkazakov · November 1, 2025, 12:07pm

Hi, @heythatsprettygood!

Tested this build with StillLife.exr and no dice. The image loads, but is extremely blown out and for some reason has an off-white background rather than the usual Krita grey

The HDR report says that, while compositor reports that transfer_function_st2084_pq is preferred, Krita doesn’t select it. Could you verify that you have “Preferred” surface format selected?

heythatsprettygood · November 1, 2025, 12:28pm

I can confirm that it is set to preferred mode. It seems this issue has just fixed itself, as for some reason some system updates I have applied between the last test and now have caused the images to no longer be blown out, and they appear to display correctly, and they definitely have different colours than SDR. However, the HDR settings are still greyed out.

Hi, @olderocean!

The report says that you have HDR enable and Krita uses it. Doesn’t the image look like HDR visually?

This is how it looks on my device:

HDR mode (all spirals are just “very bright”)

SDR mode (spirals are colored, they are not bright, just maximized SDR color of the same brightness as the square below)

Snudl · November 4, 2025, 9:51pm

For what it’s worth, I’m on KDE Plasma and KWin 6.5, and in short I can confirm HDR output works. HDR highlights are brighter than the SDR reference white level on my display, and clipped highlights are present in screenshots of the HDR canvas. I’ve been using Blender’s new HDR output over Vulkan on Wayland for some months already.

However, I have to do some tweaking to get it going and there are some quirks with the HDR.

This may be out of scope for what you want tested, but I wanted to protocol it anyway. The AppImage does not like the global menu widget or application menu in the titlebar, so I have to disable those, and I also had to remove some krita.org/krita.conf file that contained MenuBar=Disabled to even get access to the main menu. Next, I can’t enable the Canvas Graphics Acceleration checkbox in the Display settings at all. The file kritadisplayrc would always get OpenGLRenderer=none written into it whenever I tweak or close the settings, but if I overwrite it with OpenGLRenderer=OPENGL and restart the AppImage, HDR output works again. I can set Canvas surface bit depth to 10-bit in the settings, but Current canvas surface bit depth still reports 8-bit with HDR.

With the HDR canvas working, the HDR content brightness seems to be pinned to the HDR max nits value in the system settings. When I try changing Plasma’s screen brightness slider, Krita’s HDR canvas always readjusts itself to the same absolute luminance on the display no matter how low the screen brightness is set. That behavior is very different to Blender’s display HDR or mpv showing an HDR video, for example, where the HDR content exposure is scaled along with the rest of the window by the screen brightness and SDR reference nits level. So comparing an EXR image, Blender sets the scene 1.0 color brightness to the current SDR luminance and brighter color values use the display’s available HDR overhead, while Krita clips anything above 1.0 regardless of HDR, unless the exposure is adjusted to compensate.

Hi, @Snudl!

Your report has three different issues. Let’s handle them separately:

Clipped HDR brightness

the HDR content brightness seems to be pinned to the HDR max nits value in the system settings

Yes, that is the problem of KWin changing behavior in version 6.5. I have pushed a patch,
could you please try this build when it builds?
Global menu

The AppImage does not like the global menu widget

Well, it is unrelated, Krita never was friendly to global menus
Renderer selection issues

I can’t enable the Canvas Graphics Acceleration checkbox in the Display settings at all

Can you somewhat reliably reproduce this issue? I cannot get it here, but your log gives some hints. What happens if you enable “Graphics Acceleration”, set “10-bit” in the color management settings and then restart Krita? Your log says that your Krita uses 8-bit surface, which is not enough for HDR.

Could you make the following log for me?

Okay, good news and not so good news.

I’ve had some weird issue. After the first successful launch of the new Krita AppImage, both the AppImage and the distro installed Krita would throw an error on startup.

libpng error: IDAT: CRC error

fish: Job 1, 'QT_LOGGING_RULES=krita.opengl=t…' terminated by signal SIGSEGV (Address boundary error)

Now they work again, though not even reinstalling libpng, upgrading the system and rebooting solved it, the error just vanished later when I started the AppImage with my preexisting user folder.

Hey, that did it! This build Krita matches Blender 5.0. HDR test images have the same overall exposure, gamma contrast and saturation between both applications. Changing the screen brightness slider now also dims the HDR canvas, while the HDR highlights still reach beyond the SDR level just like I’d expect.

It’s interesting that the Krita HDR canvas exactly matches Blender in this case, where changing the display space from an SDR space to HDR Rec. 2100 PQ or HLG causes the viewed image to have slightly less contrast. According to Blender dev Brecht, that’s due to using both the piece-wise and gamma 2.2 sRGB function and considered the current intended behavior for them.

Oh but Krita with the HDR canvas definitely has the advantage with wide gamut images now. Blender still seems to be limited to the sRGB / Rec. 709 gamut for display output, but Krita produces brilliantly saturated colors on my display. Screenshots quite literally pale in comparison, those are limited to sRGB too.

By the way, using an OCIO config in this Krita build still results in increased image exposure. Not sure this is really what’s going on, but it seems maybe the 1.0 normalized white value gets mapped to the HDR max brightness.

Well that seems unchanged. I still can’t click on Canvas Graphics Acceleration at all. I’ve set the canvas bit depth to 10-bit but it reports 8-bit and I get a warning popup on the canvas and in the log about it being in HDR mode with 8-bit. Canvas surface color space only gives me the options Preferred, Rec 709 Gamma 2.2, Rec 709 Linear, and Unmanaged.

Could you please elaborate about this issue a little bit?

There is a huge dispute in Wayland protocol whether sRGB images should be rendered as gamma-2.2 or srgb-piece-wise-function. Krita believes that they should be rendered with srgb-piece-wise-function, since otherwise it will break the color managed workflow for non-display outputs, like printers and topographies. It is a bit distressing to hear that Blender switches to rendering srgb as gamma-2.2.

dkazakov · November 6, 2025, 10:04am

Could you please join IRC and ping me there, so we could debug this issue? It seems like Krita fails to create a trivial openGL context on your GPU, gives up and forbids openGL at all.

I wonder why it happens. Can you run normal released Krita in openGL mode? Or at least this package in XWayland mode? (do QT_QPA_PLATFORM=xcb krita-*.AppImage to test that)

dkazakov · November 6, 2025, 11:38am

Could you please try this build? krita-6.0.0-prealpha-69207b2ce3-x86_64.AppImage — Яндекс Диск

You need to run it with a different command line though:

KRITA_NO_COMPATIBILITY_PROFILE_WORKAROUND=1 QT_LOGGING_RULES=krita.opengl=true QT_QPA_PLATFORM=wayland krita-*.AppImage

The new switch KRITA_NO_COMPATIBILITY_PROFILE_WORKAROUND changes the behavior a little bit, so it might help. In return I need the console log only, it will show if the workaround is activated or not.

Snudl · November 6, 2025, 2:22pm

@dkazakov I sent a message on Matrix, but I don’t think I have an IRC account for relay anymore.

No sorry, still can’t activate Canvas Graphics Acceleration. On the Krita 5.2.13 AppImage and distro package I can set OpenGL in the menu without issue.

I can only really do a visual comparison. The Krita 5.2 canvas shows consistent contrast with Blender 5.0 Color Management Display set to sRGB and the other SDR spaces, and also other image viewers. In case of an EXR I convert it to sRGB built-in to show correctly in Gwenview. The new Krita 6.0 builds HDR canvas displays images with slightly less contrast, consistent with Blender Display set to Rec. 2100 PQ or HLG and Display Emulation set to Automatic. I added an Extended sRGB color space to the OCIO config used for Blender which allows unbounded HDR values and uses the same piece-wise function - !<ExponentWithLinearTransform> {gamma: 2.4, offset: 0.055, direction: inverse}, and that one is again consistent with sRGB and the other SDR spaces. Original context from this Blender devtalk thread.

The new Krita 6.0 builds HDR canvas displays images with slightly less contrast, consistent with Blender Display set to Rec. 2100 PQ or HLG and Display Emulation set to Automatic

Yeah, that looks like the exact result of that weird discussion, which resulted in Wayland starting to treat sRGB images as ones having gamma-2.2 space. I.e. the image you see in Krita 5.2 and “Blender 5.0 Color Management Display set to sRGB” case you see incorrect representation of your image. And the image you see in Krita 6.0 and “Blender Display set to Rec. 2100 PQ” is actually correct.

By “correct” I mean that if you convert this image into the profile of a printer, print and compare to the screen representation, the one in Krita 6.0 will look more similar to the print than in Krita 5.2 (when running on Wayland).

dkazakov · November 6, 2025, 3:04pm

Hi, @Snudl!

Could you send me the log that is printed if you run the latest AppImage (krita-6.0.0-prealpha-69207b2ce3-x86_64.AppImage) with the following command line?

QT_LOGGING_RULES=krita.opengl=true QT_QPA_PLATFORM=xcb krita-*.AppImage

It will run the AppImage in the XWayland mode, so I could compare it to the one you got in the native Wayland mode.

And does Canvas Acceleration checkbox becomes enabled in XWayland mode?

Snudl · November 6, 2025, 4:27pm

Yep, QT_QPA_PLATFORM=xcb works, I can set Canvas Graphics Acceleration and toggle the checkbox.
