When I try to put Kdenlive in fullscreen mode it glitches terribly (screenshot below). It only happens in Gnome (Wayland) (i.e., no problems in Plasma Wayland or Gnome on X11). I don’t know if this is a Kdenlive bug, Wayland bug, or Gnome bug…but I thought I’d start here.
I’m using:
Gnome 43.2 (Wayland mode)
Kdenlive 22.12.2, KDE Flatpak runtime 5.15-21.08 (x86_64)
