Description

(Please ignore the NVIDIA GPU in my hardware; it is for GPU passthrough via VFIO)

After upgrading to Linux 6.10.5 or higher, I noticed severe graphical corruption (see below) in my setup: 2 4K monitors running at 144Hz connected to an AMD RX 7900 XT. I bisected this down to this commit in the stable tree.

I also periodically switch to using KDE Plasma 6 on this system, and I never experienced this corruption before or after this kernel version there. To me this means Hyprland is doing something wrong.

I can reliably revert this commit in 6.10.10 and the problem goes away.

I can reproduce this issue regardless of the state of VRR, explicit sync, or direct scanout.

How to reproduce

(Taking a guess, as it seems I'm the only one who has seen this)

  1. Linux 6.10.5 or higher.
  2. Two 4K monitors at 144Hz connected to an AMD GPU (RX 7900 XT).

Another thing to note: when this bug occurs, quitting Hyprland or changing TTYs causes the system to hang.

I am not a kernel dev but they shouldnt break userspace so isnt this an amdgpu bug?

I have this same problem on 6.10.x+hyprland as well. Very similar setup to you with dual displays, high refresh rate. 7900XTX. The screen looks exactly the same as your photo.

could be a kernel/mesa/amdgpu bug tbh, 6.10 has been a disaster for me on amd too and I've locked kernel to 6.9 for now

0xC0ncord commented 2 months ago

It could be an amdgpu or Mesa bug. Forgive me as I'm not familiar with the Linux graphics stack at all, but wouldn't I be seeing this corruption on Plasma as well if that was the case?

This is resolved for me on arch as of (or some time prior to) linux 6.11.3-arch1-1 and hyprland 0.44.1-1.

I'll give this a spin on Linux 6.11 later today and see if I can still reproduce.

I'm no longer seeing this problem on Hyprland 0.44.1, AQ 0.4.2, and Linux 6.11.4. Thanks!
