I have two monitors. 1st monitor has 3840x2160 resolution with 150% scaling and 2nd monitor has 1920x1080 resolution with 100% scaling. When I move the app between the monitor it gets stuck between the two monitors and I have to wait about 5 seconds before I can grab it an finish the move. I see on the title bar Not Responding.

Another similar issue is grabbing the corners or sides to resize it is very jerky.
