Forgot to say I'm on Wayland, using Firefox Wayland, mesa 20.2.0, and have the following config changes:

• media.ffmpeg.vaapi.enabled is true
• media.ffvpx.enabled is false
• gfx.webrender.all is true
• fission.autostart is true

@gsf.greece and you forgot to say what gpu are you using :P
But I see the same on Mesa Intel(R) HD Graphics 515 (SKL GT2) (0x191e)

True, I'm using an AMD 5700XT. I think this started happening since wayland/x11 VAAPI code got merged, it's not from a recent change.

The issue occurs a lot when using picture-in-picture mode on Xorg with EGL backend + VAAPI. It's still unchanged with 86 beta 3.

Is this issue known to Robert Mader or Martin Stransky?

This should have been fixed by bug 1684194 (Firefox 88).
