I upgraded to the latest PopOS with Cosmic running on Wayland.
Honestly everything just worked, but using it made me so nauseous. There was some latency somewhere, never figured it out. Running Cinnamon on X11 now. I did read some suggestions to improve latency but I have PTSD so it's going to take a while before I try Wayland again.
That’s interesting. I have the opposite effect—X11 always had jank and latency, to the point that it drove me to windows for a couple of years.
This is with multiple monitors on Nvidia’s, all of which support vsync. Disabling that did help, but why would I want to?
Wayland, currently, is butter smooth.
