Strange behaviour in portrait mode

when switching screen to portrait mode I get:

  • screen stutter
  • screen tearing
  • high cpu usage/spikes (xorg)

Command I used:

xrandr -o right

I wanted to buy more of this but
I can not use this board if it doesn’t work properly in portrait mode…

Running rock-3a-debian-buster-xfce4-arm64-20220701-0158-gpt.img.xz

ow you can just do that in the display options of xfce4

It works the same - it’s useless.
