Very bad video playback
Hi, I switched to manjaro i3 from manjaro XFCE, and I am having really bad video playback everywhere. It is stuttering a lot on 720p, and it is a lot worse than it was on XFCE, basicakky unusable. I tried opening a video with mpv to see if there are any errors and I am getting this:
(+) Video --vid=1 (*) (vp9 3840x1920 29.970fps)
(+) Audio --aid=1 --alang=eng (*) (opus 2ch 48000Hz)

You haven't got opengl working.  It should be using the gpu video output.  That plain x11 output driver will be really slow.

Check that the kernel panfrost driver worked:  dmesg | grep panfrost

Then check for opengl support:  glinfo

You should see lines about panfrost that end with initialized panfrost for the kernel. glinfo should have Mesa, Mali, and Panfrost as the first few items it returns.
