1. Open a lot of the same app windows
2. Hover the taskbar icon multiple times
3. It will end up showing a blank box

A blank rectangle is seen

A line with all windows previews that shows the corresponding window when clicked

This means that the thumbnails for the windows failed to display. Since you're using an NVIDIA GPU, I'd say there's a 99.9% chance it's Bug 478309.

The issue refers to Wayland, and I'm running on X11 and I still have this bug.
Does bug 478309 happen on X11 too ?

Yes, PipeWire is used on X11 as well as Wayland.
