GDM3 screen flicker in fullscreen video and other cases

Hi, I’ve switched to GDM3 and there are cases when menu drop-downs flicker, e.g. vscode and fullscreen videos don’t work in the browser or vlc (also flicker and not really playing, just the sound). I think I may be missing some configuration for the display which was applied to LDM in the image. Any pointers would be much appreciated - thanks.

solution: edit sudo vim /etc/gdm3/daemon.conf and uncomment WaylandEnable=false
