Issue with hardware acceleration on firefox 55

Postby JoeClark » Thu Dec 21, 2017 8:41 am

Hi,
Since updating to firefox 55 videos show up as having two layers, a green and a pink one with one of them stretched below the viewport. I know that this is related to hardware acceleration, and that disabling it will fix the issue, but disabling hardware acceleration is not an option. Also I should note that my netbook is quite old, and that I have to turn on "media.hardware-video-decoding.force-enabled" and "media.wmf.skip-blacklist" in order to enable hardware acceleration.

Videos play correctly in firefox 54.0.1 and firefox 52.3.0 esr. My question is, does anyone know what changed between firefox 54 and 55 that caused this issue? Is it a regression or was there a change that removed support for older hardware? And is there any option I could change that could fix video playback on newer versions, or should I just stick with the old ones?
Please help.
Thanks!

I didn't find the right solution from the Internet.
