Dear boogiepop,
thank you for your help & assistance!
I upgraded linux-aarch64-rockchip-bsp6.1-joshua-git, deinstalled gpu-drivers for kernel 5.10 with -Rdd mesa-panfork-git mali-valhall-g610-firmware, installed pacman -Syu mesa-panvk-git and then getting wayland in my beloved xfce running (xfce wayland session). There’re some small issues but I don’t use many programs and they’re working fine and smooth.
mpv seems running hardware accelerated, when I am checking the task manager (4% cpu).
I have the same error messages as mentioned here from Baal

If there’ll be the 6.16 release for linux-aarch64-rk3588-collabora-git I’ll test it. Thanks again!
