Of note for those using Wayland/Mutter Firefox 78 now has the option of Partial Present[0] and better supported VA-API for video playback.
Interestingly there was a recently discovered Mutter bug[1] where the Culling code to prevent rendering of windows that were not visible was not working. This fix will need to be deployed to see the biggest benefit of Partial Present.

- guerrilla 6y agoWhen did they start supporting VA-API? I didn't notice. Lacking that was one of the reasons I got a new computer.

- guerrilla 6y agoOh that's wonderful. I'll get back some of the CPU of my new computer. I've pretty much have a core dedicated to it.
- agurk 6y agoIt's slightly more complex as there are some hardware/software combinations that don't work. This article gives some good steps to make sure it's enabled: https://mastransky.wordpress.com/2020/06/03/firefox-on-fedora-finally-gets-va-api-on-wayland/ https://mastransky.wordpress.com/2020/06/03/firefox-on-fedor... I've also had to disable media.ffvpx.enabled in previous versions to enable VA-API for more than just VP9 (I haven't yet been able to verify if it's needed for this one).
