Extreme stuttering with i915.enable_psr=1
Affected version
- Fedora Linux 38 (Workstation Edition) x86_64
- Issue occurs only on Wayland (as X11 does not even allow higher refresh rates on the internal screen)
Bug summary
Hi. I own a brand new Lenovo Yoga Pro 9 14IRP8.
- External monitor: Connected via DP to a Thunderbolt-3 Dock to the notebook -> 3440x1440x144
- Internal monitor: Allows up to 3072x1920x120 (but I'm running it at 1920x1200
Whenever I try to activate 120hz on the internal screen, there is extreme stuttering on it (like really 2-3 frames per second - see the attached video):
I can work around this by adding a kernel parameter: i915.enable_psr=0.
This issue occurs no matter if I'm enabling the iGPU, hybrid mode or dGPU of my notebook. For working I'm fine enabling the iGPU only.
Maybe this helps to narrow down issues around psr. I'm also open to support in further debugging and testing.
