Description Katrosh 2025-03-26 17:04:47 UTC

SUMMARY
When I use Krita, sometimes it flickers a white screen for about one frame. It happens in intervals of a couple of minutes. It never happened before, only after the new Discord stream overlay update.

STEPS TO REPRODUCE
1. Just have to use Krita as usual. Nothing different from the routine.

OBSERVED RESULT
Eventually, it will flicker a white screen for one frame.

EXPECTED RESULT
Eventually, it will flicker a white screen for one frame.

I suspect that this is a graphics driver issue. The discord overlay probably also accesses the GPU and there might be some interference. You can try to switch the canvas acceleration backend in Krita's display settings, but I'm pretty sure this isn't something we can fix, because the problems are way down the stack, and not in code we write.

Hello! Hope I can send a response here. You were right. It wasn't a Krita
problem. It is caused by the Discord overlay. Just had to disable it and it
was fixed! Well, not truly fixed, but you know what I mean. Still, thanks!
