Created attachment 181795 [details] KDE Overview SUMMARY I’m running TuxedoOS with KDE, and since yesterday it seems KDE is unable to display window previews/thumbnails. When I Alt+tab, all thumbnails are just black squares. When I bring up KDE Overview with Meta+W, it’s just a black background with no thumbnails for the windows in the current or other desktops. When I hover over a task in the task bar, instead of displaying a thumbnail with a preview of the window, it only displays the application's icon. Please see the 3 screenshots attached. I've been pointed to this ticket, I've installed `qml-module-org-kde-pipewire`, but the issue persists: https://bugs.kde.org/show_bug.cgi?id=455021 I usually use X11. I tried logging in with Wayland, but the issue also persists. Has anyone else had a similar issue? How would I start investigating/fixing this? Thanks in advance. STEPS TO REPRODUCE 1. Open 2 or more windows 2. Press Alt+Tab 3. Press Meta+W 4. Hover over a task in the task bar OBSERVED RESULT * When pressing Alt+tab, no window previews are shown * When pressing Meta+W, no window / desktop previews are shown * When hovering on the task bar, no previews are shown EXPECTED RESULT * Expected to see window / desktop previews in all of the above SOFTWARE/OS VERSIONS OS: TUXEDO OS x86_64 Host: TUXEDO Gemini Gen3 AMD Kernel: 6.11.0-116025-tuxedo KDE Plasma Version: 6.3.2 KDE Frameworks Version: 6.11.0 Qt Version: 6.8.2

Is there an NVIDIA GPU involved?
(In reply to Nate Graham from comment #3) > Is there an NVIDIA GPU involved? There is! I've got an RTX 4060. Driver's version: 560.35.03
I tried switching to iGPU mode (AMD Radeon 610M), but the issue still persists.
I'm not able to reproduce this on git-master with a laptop that has a dedicated nvidia GPU, and an integrated Intel. It's set to use the nvidia GPU for external monitors, and has the proprietary drivers installed (570.153.02)
can you open 'kcmshell6 qtquicksettings' and confirm the renderer is set to auto/opengl

Update: I've "fixed" the issue by resetting KDE and deleting these config/cache files. It may have just been some corrupted file. ``` cd ~ rm -rf .cache/plasmashell* rm -rf .cache/kwin rm -rf .cache/krunner/ rm -rf .cache/ksycoca6* rm -rf .config/plasma* rm -rf .config/kde* rm -rf .config/kwinrc ``` I backed them up in case anyone's interested in diving into this, but I suspect not. In hindsight, I should have deleted those files one at a time to zone in on the issue...
(Oh, and rebooting afterwards, of course)
I was also running into this issue on Endeavouros, but managed to fix it simply by removing the kpipewire package, reinstalling it and rebooting. Not sure what the issue was, or why a few people seem to have had it in the last month, but it at least seems to have an easy fix.

I just ran into this with kbuntu25.04/kwin4:6.3.4. I only set aside .cache/kwin and rebooted and the issue was resolved. At least for the current poweron. I've not tested if it will return after next reboot/shutdown.
