1871803 - green blocks in fullscreen videos with HW acceleration

Status: UNCONFIRMED

(Core :: Audio/Video: Playback, defect)

Description

[Martin]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:121.0) Gecko/20100101 Firefox/121.0

Steps to reproduce:

I have this issue for quite a while now, probably a few months. First I noticed it, when I watched a video on Amazon-Prime in fullscreen mode. (But it happens on any video that you can put in fullscreen mode on firefox)

Actual results:

Sometimes it takes a while, but when you are in fullscreen mode, you see a few green blocks buzzing around and then disappear again. It looks like an encoding error, since it only occurs, if you have HW acceleration turned on.

Expected results:

No green blocks buzzing around while watching any video.
