Public bug reported:
Fullscreen Firefox is not being rendered as direct scanout in GNOME 47.
Press Alt+F2, type "lg", click Flags and enable PAINT_DAMAGE_REGION.
This will show you in red when part of the screen is being composited.
When an app is getting fullscreen direct scanout, all redness should go
away. It does for Chrome, but not for Firefox.
