if this is so, I can admit I'm wrong. so not everything works for everyone.
For myself and members of my family, I can say that absolutely everything works on gnome. And I have several machines, spread over several cpu and gpu generations, and different form factors that confirm this. not only those 3 laptops I mentioned.
Could it be that since you are not using gnome that you are hitting those problems? My experience is exclusively gnome, so maybe this is it?
a11y aside of course... given that this was not really finished. or seriously worked on.
