Hello guys!
I was wondering if someone had the same issue (or at least has an idea how to fix it).
Here what I have while drawing.
In other words while I use tool a small lines appear in a view next to the cursor, but it does not affect the image itself. Seems like a viewport rendering issue.
I am on Windows 10, my displaye is 25" Dell UltraSharp U2518D (210-AMRR).
I tested it on freshly started OS.
Any ideas how to fix it would be appreciated.
(edit), Forgot to mention. It is Krita 4.4.8
Hi, yes. This has been reported more often recently. Coincidentally I just filed a Bug report about this (and included your example too)
https://bugs.kde.org/show_bug.cgi?id=441649
Do you use System UI scaling by any chance? I think your Display is at leas 1440p in resolution, right?
try to Switch OpenGL to Direct 3D
Yes the resolution of my screen is 2560x1440.
And yes I have “Enable Hi-DPI support” and |(Hi-DPI) Enable fractional scale factor" both enabled.
Actually I have Direct3D enabled by default. Tried switching to OpenGL - no effect.
And your Windows System UI scaling is probably at 125% or something, right?
Exactly.
It is a recommended setting.
Dos the artifacts appear only on the scratch pad or do they also appear on the canvas? Just asking because the screenshot seems to be from the scratch pad in the brush settings.
Mostly on a scratchpad. Though it was appearing on a canvas as well. That is why I actually came her.
But for some some reason now I cannot reproduce same behavior on a canvas. I will try to catch when it does artifacts on canvas too.
Currently the only way to get rid of the lines seems to be to set the scaling to either just 100% or 200% (the later makes everything too big for me, even on my 2160p screen) however, maybe 100% would be an option for you. I think Windows now supports per application scaling so you could only set a scaling factor for Krita. As a Manjaro user, I’m stuck with it since it only supports global scaling, unfortunately.
I noticed that for me the issue depends a lot on the brushes used. with some it is basically unusable, others have only minor or no issues.
I just been told that “enabled factional scaling” is actually causing this. What happens when you disable it in the Krita settings?
Yeas. Seems like that was causing the issue. Unchecking the setting made such that artifacts are not appearing anymore.
That probably disabled the scaling of Krita altogether but at least it’s working.
Yeah. UI became slightly small after that. I can live with that. It much better without artifacts.
Thanks for the help. I will try to enable this setting on newer versions (maybe the issue will be fixed)
