There are still so many issues around Wayland and fragmentation. Gnome is the most popular and has lots of issues and sometimes is downright user hostile. Luckily some of the distributions try to revert some of the insanity sometimes. But there are still many protocols and portals needed and much more standardization.
I handed you the fix to nearly every issue you listed, and you won’t take it. That’s a you problem.
Another factor is hardware friendly to Linux. We have multiple laptops here with different components, different distros X/W etc, and all working great… at least as well as mac or win ones.
