Minecraft freezes when minimized / ALT-TAB / Switching Window Focus

If I launch a snapshot Minecraft, then minimize the Minecraft window then maximize it again, my screen will be frozen. The game still works, as I can still hear button clicks and I can break blocks on a server, but my actual screen stays exactly the same as it was when I opened the window back up.

I have not attempted to reproduce this on someone else's computer, but I thought I would post it here anyways to see if anyone else has this problem.
