Teams window got out the monitor limit if using multiple monitors
If Teams window is maximized on one of multiple monitors it got out the monitor limit, and you see a little part of teams window on other monitor.

I also just discovered this issue. It has soon been 2 years since submitted here, but I realize that there are other issues that are more important.
Yes, this is so frustrating to make a maximize every time when I start the Teams on multimonitor setup.
