Thanks. I can see two potential problems so far: 1. The 'variable-refresh-rate' experimental feature is enabled. It's not mature and still buggy, but also probably has no effect in Xorg sessions. Still, I recommend disabling it for now because it's known to cause a number of bugs.
2. You are using fractional scaling in Xorg. This is a custom Ubuntu patch that is known to cause image clarity problems and performance problems. To avoid these issues I recommend choosing a scaling factor that is a multiple of 100%, or logging into a Wayland session if you need fractional scaling. If those don't solve the problem then I have more ideas but they will require more information which can be gathered by running: xrandr --verbose > xrandr.txt sudo apt install drm-info sudo drm_info > drminfo.txt and then please attach the resulting text files here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2119415 Title: Video configuration problems: results are destroying my eyes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2119415/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
