xwayland redrawing is very bad
It is so bad (see video) I imagine that a warning like it is in one gtk-demo for epileptic seizures needs to be added for using xwayland (dark theme and white window damage):(
Affects me with:
Radeon RX 570 Series (POLARIS10, DRM 3.38.0, 5.8.17-300.fc33.x86_64, LLVM 11.0.0)
xorg-x11-server-Xwayland-1.20.9-1.fc33.x86_64
Tested on gnome (where it is always bad) and wayfire (/wlroots which was used to take the attached video) The video shows also that it's less bad with a wayfire plugin that causes windows to redraw constanty (wobbly), that is not available on GNOME though, where it's always bad.
Here a link to the video https://drive.google.com/file/d/1oM0cXpeS8lghDFN2fspgrIVBs3f9N0d-/view?usp=sharing
