Using "adjust all fonts" in the fonts KCM to change the font, then clicking Apply, I get the panel corruption in the attached screenshot. The same corruption seems to extend to the desktop wallpaper too.

Restarting KWin or Plasmashell seem to clear up the issue.

Setup:
- Plasma from a recent git snapshot from Tumbleweed repos
- nvidia gtx770 with the nouveau kernel module and the modesetting driver
- X11
- Mesa-dri-nouveau-21.3.4, libdrm_nouveau2-2.4.109
- kernel-5.16.2

Definitely NVIDIA-related.
Comment 2 Ahmad Samir 2022-02-02 17:20:31 UTC
(It affects the whole plasmashell, not just the panel).

Comment 4 Ahmad Samir 2022-04-03 19:16:45 UTC
I think it's not a duplicate, since I am using X11 and the nouveau driver not the nvidia proprietary one.

Oh ok.

Adding the x11-only keyword
