Comment 90 for bug 1968040

Hey Daniel. Your comment made me look closer at what was happening and I found the culprit in my case.

I have 2x 1440p screens connected through the dock, that support up to 165hz, and the dock supports enough bandwidth to run them at 1440px60hz. But when it wakes up from suspend it for some reason puts the screen settings at 1440px144hz. The same doesn't occur in xorg which is why the issue was isolated to Wayland for me.

After I woke my laptop from suspend, changed the display settings to 60hz, everything worked again. After changing it once it also seems to persist for now.

One other observation though, in xorg I can't even set my screen hz higher than 60 while Wayland gives me the option to crank it up to 144hz. When even trying to set it to 144hz, my monitors OSD tell me it still runs 60hz while gnome settings thinks it's 144hz.

Either way, I apologize if I wasted your time but I hope that it was helpful for others who might end up here trying to find a similar solution.
