Alt-Tab causes screen alignment errors

[MHertz]

I am experiencing problems with multi-boxing and additional monitors that I haven’t seen previously. This may be due to a recent change in video display; I noticed it about 2-3 days ago.

• Some screen display options disallow Alt-Shift-Arrow (to move one instance of the game to the other monitor)
• Some screen display options are offset by the height of the Windows Task Bar, resulting in mouse displacement (what you hover over is not what gets clicked on)
• Activating an idle game window can cause the previously-active game window to spawn the Windows task bar

I have not yet noticed if there are specific video settings (eg, 1920x1080, 1920x1080 desktop, Borderless monitor 1, etc) that tie to certain behaviors. Mostly, the options appear to work at first, but then experience problems after Alt-Tab occurs. I will keep testing.
