ADDITIONAL INFORMATION

Comment 1 Julien Delquié 2021-10-27 08:13:13 UTC

Also, if I relaunch plasmashell from console, I have many many many messages like this:
qt.qpa.wayland: Could not create EGL surface (EGL error 0x321c)

An example of the issue

Desktop with no Wallpaper, no visible Panel (but exists), 2 consoles with transparency+blur, and calendar opened from clock in the right corner but nothing appear just the transparency+blur effect on it.

Comment 3 Julien Delquié 2021-10-27 08:51:48 UTC

Trying to force gui-libs/egl-wayland from 1.1.7-r1 to 1.1.9 seems to make things better, I have a wallpaper, no messages about EGL error, but everything is really slow, the panel appears only if I put my mouse on the bottom edge, but panel does not work at all and makes plasmashell crash many times.

Yeah it's a known regression in egl-wayland 1.1.8.
