I had the same issue with Ryzen 5 3600x and Radeon 5600xt. For a different mouse flickering issue when using xrandr, I had to set following xrandr after I set correct resolution and panning.
xrandr --output DisplayPort-2 --scale 0.9999x0.9999 DisplayPort-2 is my primary display. With the above setting my mouse flickering went away. Surprisingly this also fixed the screen flickering issue after wake up from suspend. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1874588 Title: Flickering screen after waking up from Suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1874588/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
