Hello.
Tried LM22 Cinnamon Beta and sadly had to go back to LM21.3 with timeshift. There was some instability problems with the screen. I have noticed that with some distros with newer kernels my 6 y.o. laptop did not seem to like them. My laptop is not new but (I hope) not old yet but it does have a repaired mother board. The instability made the screen jump a bit and was really bad while playing gnome-games. Almost bad to the screen blinking point of last thanksgiving. Was annoying. Back to LM21.3 without any problems.
I have even older Dell laptop that also does not seem to like newer kernels but the instability is very much not a problem. On both laptops the live USB take a very long time to load: more than 4 min.. LM 21.3 takes not even 1 minute.
But apart from this screen instability, LM22 was working good. The screen jumping was just annoying.
