Flickering/Looping html5 videos in Firefox with radeon


Since the last update, whenever I see a video it gets flickery. That is not the usual flicker where it very shortly fades to black or something, no, it gets stuck. A small portion of the video loops back and forth in abrupt intervals. Actually looks kind of funny.


I'm using a Hd 7950, FF 50.0, glxinfo says:

Extended renderer info (GLX_MESA_query_renderer):
    Vendor: X.Org (0x1002)
    Device: AMD TAHITI (DRM 2.43.0 / 4.5.2-1, LLVM 3.8.1) (0x679a)
    Version: 12.0.3
    Accelerated: yes
    Video memory: 3072MB
    Unified memory: no
    Preferred profile: core (0x1)
    Max core profile version: 4.1
    Max compat profile version: 3.0
    Max GLES1 profile version: 1.1
    Max GLES[23] profile version: 3.0
OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD TAHITI (DRM 2.43.0 / 4.5.2-1, LLVM 3.8.1)
OpenGL core profile version string: 4.1 (Core Profile) Mesa 12.0.3

I think that should be the relevant info, but please just say if something is missing, I'd add it.


I have no idea how to debug that and found no similar bug, does maybe someone have an idea how to tackle this one?

Just reporting back that the upgrade to FF 50.0.2 is indeed not sufficient. Worked a while but the issue just re-appeared when viewing an embedded youtube video. Turning off hardware acceleration seems to help, but is of course not a good long-term solution.

Please post the link to the video so we can test it.

That's not how this bug works. Videos work for a while and then not. For example, I watched

just fine an hour ago. Now FF started to misbehave (when starting the first embedded video in http://www.nexusmods.com/skyrim/mods/53996/?[writing a skyrim mod article for a gaming magazine]) and it is not working anymore.

I experienced this issue and found it to be related to multi-process tabs.  My browser starts by default with it disabled - I haven't been able to identify exactly what is disabling it.  If I force it enabled then video plays fine but I encounter frequent tab crashes for certain sites.
