[SOLVED] Firefox: Videos freeze in fullscreen - unless mouse is moving

Over the last couple of weeks, whenever I try to play fullscreen videos in (v. 47.0), they play for about 5 seconds then freeze.

If I then I wriggle/move the mouse, the video will resume playing, but as soon as I stop moving the mouse, the video freezes again. Videos play fine if I don't full screen 'em.

Full screen videos play fine on Chrome, and I can play full screen vids on Kodi and MythTV and other video apps just fine.

I have disabled flash completely, and Firefox is set to use HTML5 wherever possible. I've disabled adblocking. I've also tried using a default/new profile. All videos do this, even 240p.

Hardware: Intel NUC 5i5RYK, with latest intel drivers. Gnome-shell - tried both wayland and X.

[EDIT: It's not just youtube, same symptoms on vimeo).

[EDIT 2: Looks like I'm not the only one: https://www.reddit.com/r/firefox/commen … t_moving/)

Re: [SOLVED] Firefox: Videos freeze in fullscreen - unless mouse is moving

Kernel 4.6.1 and 4.6.1 are suspicious.
Temporary solved by one of these solutions : -

1.Using Chrome.
2. Using LTS kernel.
3. Avoid using flashplugin in firefox.
4. Patch the 4.6.2 kernel  with
  - https://patchwork.freedesktop.org/patch/79567/  and
  -  https://patchwork.freedesktop.org/patch/80857/ and
  -  https://patchwork.freedesktop.org/patch/94003/

Thanks. Solved / worked around by removing xf86-video-intel as per the following thread:

Re: [SOLVED] Firefox: Videos freeze in fullscreen - unless mouse is moving

I had exactly the same problem. Simply changing SNA acceleration to UXA has fixed this issue for me. - Kernel 4.6.4-1 and enable_fbc=1 -

$ cat /etc/X11/xorg.conf.d/20-intel.conf 
Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod" "uxa"
EndSection

I have the same problem but in Wayland seems to work well. Firefox 47, kernel 4.6.4, Intel Broadwell Graphics 5500.
In the latest update for xf85-video-intel changed to "DRI" "3", I don't know if I could change to UXA or other.

Re: [SOLVED] Firefox: Videos freeze in fullscreen - unless mouse is moving

Thank you so much! I'm on Fedora, and removing xorg-x11-drv-intel solved the Firefox issue but also https://bugs.freedesktop.org/show_bug.cgi?id=97818 .
