I'm seeing high CPU usage on YouTube after recent updates on Xubuntu. I think it started when they enabled GPU acceleration by default. Previously I could watch even FHD videos without much fan noise, but after recent updates, fans spin at the max speed by playing even 480p quality vids. Anyone else?
It's very very very simple and quick, there is a video demo and a text explaining what to do, and then you can open a bug at https://bugzilla.mozilla.org/enter_bug.cgi?product=Core&comp..., with the profile link (you can login with a github account or email). This will be triaged and hopefully we'll understand what's up. Please use a Nightly build or a Mozilla-provided build when doing so (so there are symbols). It's just a matter of downloading and untaring the tarball.
Please also attach a copy of `about:support` raw data (button at the top), so we can understand what your configuration is: desktop Linux systems can be pretty diverse and sometimes it isn't clear what works, what doesn't and why.
If you're playing 480p, then youtube might be serving you AV1, and this is (for now) using the CPU (trading a lot less bandwidth for increased CPU usage), you can check the codec it's using by right clicking on the video and clicking on `Stats for nerds`, there is the codec string. You can adjust your codec preferences in your youtube profile I believe.
