Armbian tearing while browser sites exploring

[Ilya]

Hi. I am using Khadas Edge 2 Rockchip RK3588S with Armbian Minimal version.

I have installed xorg and firefox browser. After "startx" I rotated display (xrandr -o left) and run firefox.
I don't know how is it calls, but I get a big gap when scrolling the website. In xrandr -o normal, it's gone. 

I will attach the video.
Help me please.
Thanks.

I would advice to try with gnome (ubuntu-desktop) 
That uses wayland, so might give another result(better or not...). Also be sure to install the gpu and vpu drivers as mentioned on the download page(only Armbian Jammy)

Hi NicoD. I've watched your videos a lot. I was try to use it with Ubuntu with Xwayland, there is ok, no lags, but I should to use Armbian minimal for the "kiosk mode". Now I use Armbian bookworm (debian) and I benchmarking gpu usage with glxtest and glxgears. GPU acceleration - works.
 There is a strange things, landscape orientation is ok, portrait is not. It can be some bug between x server and arm gpu?
