KDE not displaying any window previews / thumbnails

Hi,

Since yesterday, 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.

Has anyone else had a similar issue? How would I start investigating/fixing this?

Thanks in advance.

Hi! It might be worth trying some of the steps that resolved this older bug for folks - 455021 – Tooltip with black window preview when I hover over a task on Wayland - maybe checking that the kpipewire package is installed correctly?

Thank you for the hint!

I installed qml-module-org-kde-pipewire (looks like it wasn’t installed before), rebooted, but the issue persists :confused:

Also, I hadn’t thought of checking the tooltips, but yeah they’re not working either, they don’t display the window preview.
However, instead of displaying black tooltips, I’m getting tooltips with the application’s icon. Screenshot attached.
