No pressure at first stamp in floating dock mode

Type of device : Display Tablet
Brand and version of the device: Cintiq 13HD
System: Windows 10

Description of the issue (you can include screenshots):


I lost pressure sensitivity at first stroke after switching from float docks (I use brush preset, history of brushes, artistic color picker) . It doesn’t happen each time, but quite often ( here the video krita first stamp float dock bug - YouTube ). In attached dock mode all OK. The same effect if I switching from other program e.g. browser or video player back to Krita.

This seems like a bug. I can’t reproduce this on linux system. may be somebody with windows system can reproduce and we can report this.

I made repost to kde forums ( https://forum.kde.org/viewtopic.php?f=139&t=163700 ). I will write here if something will be figure out.
P.s. big Thanks to the creator of this forum, here all is much comfortable and simple :slight_smile:

To be honest, I don’t think you have a bigger chance to get an answer there than here.

You can check Configure Krita -> Tablet Settings -> Tablet Tester, making a few strokes and checking if any of them has P = 100 at the beginning of the stroke.

And try tips from here: https://docs.krita.org/en/contributors_manual/user_support.html#quick-solutions

Thank you, Tiar. Some info from krita docs was helpful.
All matter is “Windows Ink”. Working in Krita closely I begain 2 month ago. So in my photoshop experience “Window Ink” is absolute evil, so it was disable in drivers for Krita and in the program config also. After switching to “windows ink” all began work like a charm.

Well. Windows Ink is a half-solution. Switching to Windows Ink get other lags (discussed it here Dizziness from Rotating Triangle of pop-up Palette) and involves not only Krita but other painting software too.

The current “First stump” issue is only Krita “feature”.
I tested it with the same result on various systems:
Ryzen 1600 + GTX960
Athlon 200GE + internal GPU
I3 6100 + internal GPU
i3 4030 + internal GPU
Windows 7, 8, 10
Intuos5, Cintiq 13hd

And I wonder, if it I so lucky or nobody use undocked docks in Windows + Wacom? I just think to make a bug report but want to be sure that I’am not alone.
Could anybody who use Windows + Intuos or Cintiq make a test and post a result here?

I have Windows 10 (not used much) with a Wacom Intuos Draw. I also have floating dockers on a second monitor.
I don’t have this problem with version 4.2.8. I’ve just tried it and if I select a floating docker then I can paint on the canvas immediately with no difference between first stroke and future strokes. This is the case if the docker is floating on the second monitor or on the main monitor. It’s also the case if I switch to and from another application such as a browser.

[I do have a problem in that my maximum pen pressure is 49.9% but this has been present for a while and this is what I expect from Windows and its updates and I’ve stopped bothering trying to fix things.]

Thank you.
Hmm, Intuos Draw stylus is quite different from Intuos pro-type styluses. May be it use differ driver or something…
And 50% from 1024 levels is would really bother me…

Up. Need the testers with Intuos (from 4 to Pro2) or Cintiq + Windows to verify the bug.

I use Windows 10 version 1909, and a Wacom Cintiq 13HD as well. Krita version 4.2.8.
I usually have things docked, but when I undocked the Advanced Color Selector to test this, I noticed the same bug!


I tested it in other programs (GIMP, Clip Studio Paint, PaintTool SAI Ver.2 and Affinity Photo) just to see if this is just some wonky Windows behavior, but those didn’t have that problem! Only Krita acts this way!

Thanks, @Rakurri. Ok, I will make bug report.
Could you tell you wich kind of CPU + GPU do you use?

Have you tried using Weighted stabilizer and “Smooth Pressure” turned on? It might help with the issue, at least with those cases when it’s in the middle of the stroke.

For me it happens literally as “first stamp”. “Weighted” smoothing doesn’t help. Smoothing “Stabilizer” with higher delay option makes it happens rare (in 500px 1 per 20 strokes).

Turns out that it is problem of Qt. But @dkazakov made workaround, so I tested the Krita 4.4 beta and seems it works pretty well.
