I'm testing with empty profiles on both, so they have exactly the same config.
package.use: www-client/firefox -jack -libproxy -screencast hwaccel -selinux -sndio -wayland -wifi

Any idea, guys? I don't know where to go from here. MOZ_DISABLE_RDD_SANDBOX=1 didn't help. I'm not sure if I should report this directly to the Mozilla team, since it's working fine with the bin version.

| Try to compile Firefox with +wayland use flag. And yeah, there were some specific about:config options, especially enabled for firefox with +hwaccel. |

I recently found setting media.webrtc.hw.h264.enabled to true helped, though I didn't get as far as checking the debug trace to see what was happening.

Dead on.. I'm under Xorg, but even then I needed to set the wayland flag in order to get the hardware decoding to work. For further reference, I kept the other flags.
Thanks, man

Thanks for the tip, but recently HW decoding works here without changing any flags. Firefox seems to fix a lot of stuff related to it in the last versions. |
