Public bug reported: I've been experiencing pretty bad screen tearing on 17.10 on my XPS 13 9560 with Kaby Lake. I did not experience this on 16.04/16.10 and IIRC not even on 17.04.
After a lot of hit and trial, I was able to fix the issue completely by disabling Intel PSR mode in Grub config. Change `i915.enable_psr=1` to `i915.enable_psr=0` in `/boot/grub/grub.cfg` fixed the problem for me but I think this disables some power saving features. ** Affects: xserver-xorg-video-intel (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1714749 Title: Screen tearing with when PSR is enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1714749/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
