After the xorg-server 21.1.20 update (same with 21.1.19), I have low Hz / FPS / stuttering in desktop (noticeable when moving any window), somewhere between 30-60 Hz. If I sudo downgrade xorg-server back to 21.1.18, moving the windows is smooth again.
I’m running a fresh EOS installation, Linux 6.12.57-1-lts (same issue with 6.16, before I decided to do this new EOS LTS kernel installation; and the same issue with 6.17 (EOS installed 6.17 alongside the LTS kernel, which is fine)), nvidia-dkms and all current updates. The display is a QD-OLED TV.
Same issue here though sudo downgrade xorg-server=21.1.18 did not seem to fix the issue for me yet. Did you have to downgrade other packages too or do some additional steps?
There is a thread on the Arch forums and an issue on the Xorg/Freedesktop GitLab about it. Unfortunately, I’m not knowledgeable enough regarding Xorg to really contribute meaningfully but maybe others here can?
Thanks for the references, good to know it’s known issue.
Only downgrading to v21.1.18 fixes it for me fully.
PS: Forgot to mention, my hw is a 4070.
