That 2nd monitor window thing sounds like a DPI scaling issue, especially if your main screen has different scaling than the one causing issues. I get this a lot at work because of my setup and the software I use (on windows btw) and I got so used to manually moving the window and smashing it against the top of the screen to maximize it that I don’t really mind. But maybe the term can help you troubleshoot it further

I thought that too, and things got better when I set 1x scaling on both (it was 1/1.5) but it’s not stopped the problem entirely.
