1831745 - Damage reporting on youtube too big / not clipped to video area

Status: RESOLVED DUPLICATE of bug 1798206

(Core :: Graphics: WebRender, defect)

Attachment: Gnome damage overlay for Firefox on Youtube

When watching youtube videos, at least on Linux, the damage reported to the windowing system is bigger than necessary (see attached images - the damaged area has red overlay). This is detrimental to performance and especially battery time.

This is both with the default EGL backend as well as the experimental "compositor" one. I'm pretty sure this is a regression, but have yet to bisect.

Click on the wheel icon: Do you have Ambient mode enabled?

Oof, yeah, indeed - and turning it of makes firefox report only the video area. Ok, sorry for the noise then!
