I have the same issue on Thinkpad X250 on 20.04 with the following config: ``` Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "uxa" Option "TearFree" "true" EndSection ```
resulting in being unable to use plasma wayland sessions, random system freezes and strong flickering in sddm. purging `xserver-xorg-video- intel` solved the issue for me -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1864778 Title: Intel Drivers Artifacts after Mesa-Dev Update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1864778/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
