Broken desktop effects on KDE (maybe video driver issue)

Jason P. · 2022-07-15 19:20:01

Hi,

I'm not sure if this problem is strictly related to KDE or it's a bug on the video driver, but it hasn't been fixed for a couple of weeks with latest updates and I don't find similar reports anywhere.

While changing between virtual desktops the whole screen flashes for a brief period of time and I can see the wallpaper. It doesn't happen the smooth slide transition from before. Enabling/disabling the effect doesn't fix the problem. It really looks like a video tearing thing.

Moreover the transparent background of Latte Dock doesn't work and it's solid white.

I've noticed that corners in windows show a little black arrow when on top of a white background, as if they were a rectangle in fact. Probably it is the case but as a user I could never perceived it before.

It looks like decorations are broken on my KDE installation.

Btw, this is a Thinkpad T14 AMD with Ryzen 7 Pro 4750U processor.

Thanks.

Which video driver?
What GPU?
Xorg or Wayland.

All smooth here on Xorg and Intel Iris Xe graphics

Drop the xf86-video-amdgpu package.
If that doesn't help, post
