Possibly an NVIDIA driver glitch. I can't reproduce this with an AMD 780M iGPU. (In reply to Nate Graham from comment #1) > Possibly an NVIDIA driver glitch. I can't reproduce this with an AMD 780M > iGPU. Is there a way to test this? I tested on Plasma 6.3.0 on a system with an nvidia GPU and was also unable to reproduce On my nvidia system, I'm using the 565.77.556 proprietary driver (the reporter is using 570.86.16) I seem to be lucky enough to find bugs that don’t concern others It seems very strange to me that this stops happening when turn on the screen recording (obs, Spectacle) For what it's worth, I can reproduce the flickering after a lot of mouse movement with the NVIDIA 570.86.16 driver, but screen recording doesn't fix it. Is it safe to say this is an issue with that NVIDIA version?

I don’t know, it’s still happening with 570.124.04 and I can’t install older versions of the driver as they won’t work with my kernel This problem is still relevant. Is there a more specific way to determine where the problem occurs ? I can try report it as an nvidia bug , but for that i need to accurately determine that it’s an nvidia bug, not a QT bug, like it was with Krunner and qt 6.8. Linux: Manjaro 25.0 KDE Plasma Version: 6.3.91, wayland KDE Frameworks Version: 6.14 Qt Version: 6.9 Nvidia video driver: 575.57.08 witch close kernel module Perhaps the more detailed debugging information might help - can you please attach the output of: drm_info (you'll probably need to install it from your package manager) qdbus-qt6 org.kde.KWin /KWin supportInformation (if qdbus-qt6 is not found on your system, try qdbus6) Also please add QT_LOGGING_RULES="kwin_*.debug=true" to your /etc/environment file, reboot, reproduce the problem again, and then immediately upload the output of: journalctl --user-unit plasma-kwin_wayland --boot 0 sudo dmesg Thanks!

This problem is still relevant.

Based on the screen recordings, they do look to be the same bug. We have narrowed down that the bug was not able to be reproduce on an AMD GPU, but can be with NVIDIA. It may be related to a specific NVIDIA driver version/ versions (In reply to TraceyC from comment #18) > Thanks for highlighting that other report.

It may be related to a specific NVIDIA driver > version/ versions I know that this issue is not reproduced on AMD video cards. Just trying to figure out where the problem is. Not so long ago there was a case when Krunner crashed on second open, many also blamed the Nvidia driver , as it turned out later the problem was in QT. I’m ready to open the discussion of the problem on the nvidia forum , just wanted to get confirmation that the problem is only in nvidia and nobody else. Since the first bug description, the video driver has been updated several times, so It does not appear that the problem will be fixed in the next update. Don’t want to sound annoying, I understand you have a lot of things to do. Isolated textures disappearing doesn't strike me as bug in the graphics driver. My gut feeling is that this is z-order related and that the windows don't "disappear" but drop behind the background (also because the mouse moving and therefore focus shifting seems necessary to trigger/toggle this) If the z-order isn't actively controlled but kwin/QSG relies on implicit behavior of the driver, this could explain different ambiguity resolution.

Created attachment 178203 [details] video SUMMARY Overview effect for open applications(present windows - current desktop) and desktops(win+g buttons) glitch when move mouse cursor. This problem disappears when trying to record screen (which is weird), had to record video on the phone. STEPS TO REPRODUCE 1. start "Overview" effect 2. move your mouse cursor 3. ...... OBSERVED RESULT Overview effect glitch EXPECTED RESULT Overview effect work without glitches. SOFTWARE/OS VERSIONS Linux: Manjaro 25.0 KDE Plasma Version: 6.3, wayland KDE Frameworks Version: 6.10 Qt Version: 6.8.2 Nvidia video driver: 570.86.16 witch close kernel module ADDITIONAL INFORMATION To make the video fit by weight, had to use AV1. Make sure you can play it.
