Wanna try with panfrost support ? If you want to play around and do some testing?
Install mesa git using this command
sudo pacman -S mesa-git This will ask you to remove mesa just say yes to it.
Then make replace none with glamor in this file > /etc/X11/xorg.conf.d/01-panfrost.conf
Reboot. Hopefully you should have panfrost support with faster app loading and other Graphical elements loading with the help of GPU, there are still some glitches though. If you want to revert back then just make glamor to none and install mesa instead of mesa-git
sudo pacman -S mesa
Good Luck
