User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:149.0) Gecko/20100101 Firefox/149.0

Steps to reproduce:

Enable gfx.webrender.layer-compositor, open some sites, scroll around.

Tested on Fedora 44.

Actual results:

Pretty bad tearing on scroll and video is broken (green).

Expected results:

Nothing? Used to before 149.

PS: it's not really tearing, just parts of the content area render out of place.

Just FYI, this came back for me in 153.0 (GNOME Wayland with gfx.webrender.compositor.force-enabled enabled).
