We'll be painting to a framebuffer that may not be completely covered by the painted areas, meaning the not painted areas would end up undefined, thus potentially contain garbage or old content. Avoid this by clearing the framebuffer before painting the stage. Closes: https://gitlab.gnome.org/GNOME/mutter/-/issues/1442 https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1459
