Yeah, I thought I'd ticked something similar during setup, but maybe it wasn't for that. I installed them and it hasn't really changed anything in either mpv or Firefox.
The compositing in Firefox is webrender (software) and appears to be using llvmpipe as the GPU. There's a 2nd "GPU" listed, but doesn't seem to use it All the codecs say hardware is disabled...
Installed VLC and that seems to use the hardware renderer. MPV and Firefox are both installed with Snap. I'm seeing a pattern that might not be there, but I'm already hating Snap. This is day two of my rebooted Linux experience...
Yeah, tried all that, and not having much luck in Firefox and MPV. VLC fine. Replied to the other post, and it might be Snap blocking it. I dunno though, because I know basically fuck all about snap other than a lot of Linux people don't like it.
