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?
