Thanks for your time and reply, and clarification,
I am newbie at linux, so i am trying just to understand how the things works...
So, maybe i can stick with rpi4 and can live with it...? As you said, its a long way, and rpi4 is maybe better choice to future, due to supported SW by devs?
But i have one more question. Can you explain me, why Android OS, which is based also on Linux is working smoothly? 3D / 2D graphics, no tearing, everything is going nicely... Are there different drivers? Or what is the point?
Thanks,
