Subject: [PATCH] windisplay: Don't try to activate window when resizing/moving
 it

This fixes an issue where if you quickly alt-tab when the window opens, it receives a WM_ACTIVATE event and thinks it continues to be active, which causes issues with applying cursor confinement.

I think you can probably still reproduce that issue, but your reflexes have to be significantly more ninja now.
