Description Gavin Williams 2023-05-05 10:53:53 UTC
SUMMARY

Using Krita, from the first day of usage I am seeing sporadic flickering of the window (black frame).


STEPS TO REPRODUCE
1. Use default Krita to work with a .kra file.

OBSERVED RESULT

Occasional black frames across the entire window.


EXPECTED RESULT

There shouldn't be any flicker.

SOFTWARE/OS VERSIONS
Windows:  11 22H2 (OS Build = 22621.1635)

ADDITIONAL INFORMATION

I run with HDR on, my GPU is a 3070 TI. My display is a Samsung Odyssey G7 10 bit HDR 660 nit display. I've tried some different color profiles in Krita. I haven't noticed any different behavior. Though I don't think it flickers if the window is not in focus, so it seems like the flicker may be in response to interacting with the application, like maybe when the mouse passing from one element to another. But it's not predictable.

Possibly related - If docked to half screen, pressing the windows key to bring up the windows menu can cause the Krita window to momentarily render incorrectly, and desktop icons will render over the window, as though it's transparent for a frame.

Could you please also attach the output of help->system info for bug reports and help->system log for bug reports?

Hi, Gavin!

It would also be very useful if you could make a video recording of this flickering...
