yeah, I added config to xorg.conf which contains this: Section "Device" Identifier "Card0" Driver "intel" BusID "PCI:0:2:0" Option "DRI" "3" Option "TearFree" "true" EndSection
I have no deep understanding about how to switch drivers or how to use another one(which one?), but without this config, I had following problems: a) Option "DRI" "3" when this is not present it causes that strip of screen from time to time flicker - i would describe it like subset of pixels in some rectangle area are swapped to another color for a period of half seconds, and then it turns back to normal. It does not happen often but occasionally. b) "TearFree" "True" - without this when window is moved from up to bottom it is clearly seen that left part of screen is updated earlier then the right one. Is there a way to switch to another driver without losing this configuration? also in Wayland does not work x11vnc, and I did not found suitable replacement. -- 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/1986583 Title: Screen after some time get shifted and starts to overlap To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1986583/+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
