--- Comment #7 from Angel Parra <[email protected]> --- Created attachment 192855 --> https://bugs.kde.org/attachment.cgi?id=192855&action=edit drm_info output when background is dark (1/2) > Okay, at least that won't affect the release then, since overlays are still > off by default on AMD. I would not be so confident about that. According to nvtop, plasmashell is running on my AMD iGPU (device 1 in my setup) with only Graphic type, and then there are three instances of kwin_wayland processes all with the same exact command line arguments and same xwayland-xauthority. One is running on my AMD card (dev 1) with TYPE Both G+C and the other two are running on my Nvidia GPU (dev 0) with TYPE Graphic and TYPE Compute respectively. The one that has the highest GPU usage of the three is the one that's running on the AMD card and the other two that run on the Nvidia GPU mark their GPU usage as N/A. For further testing: I commented out the variable on /etc/enviroment and found that the flicker doesn't trigger if there's a window of Konsole, Dolphin, System Settings or Kate in the same virtual desktop, even if they're all behind the Chromium/Electron app behind. As soon as I minimize all of them or move them to another virtual desktop, leaving only the Chromium window, I can reproduce the flicker again easily. Seems like Qt windows avoid the overlays to either kick in or kick out, I'm not sure, and thus the "default" background seems to be the darker one (as per the video). I've attached what drm_info prints when the background is lighter and the background is darker as you can see in the video. You may run a diff and find that some values besides the IDs are different from each other. (I used the git version of drm_info). Additionally, besides pure Chromium window, this can also be reproduced with webapps such as Proton Mail (that also run on Chromium), and it doesn't seem to happen with Steam and Ferdium even when both are Electron apps. -- You are receiving this mail because: You are watching all bug changes.
