Have you tried switching to Wayland?
How can people be having this kind of conversation while also claiming this is the state of the art or the gold standard in 2021? I've been running macos since 2012 and never had such issues. That's over 10 years ago. Of course, OS X is older than that, and as far as I can tell, it never had such issues.
Keyboard navigation (moving between or selecting words or lines of text) still seems somewhat hit or miss even though it is better than when I left Mac OS behind in 2012.
Of course this might not matter to you (and I even know some of you prefer the separation between "application switching" and "window switching") but for many of us these are way larger issues than having to fix a config file once.
