Unity 4.5.3, when you launch fullscreen a small white window appears briefly. Attached screenshot showing this for the AngryBots project. I reported this via the Unity Bug Reporter a couple of weeks ago, but I’m curious if others have noticed this. Not a huge deal, but hopefully this gets addressed soon.
I’m also getting this issue, would love to know if it’s a Unity internal problem or something that I can code/hack around somehow.
I logged a bug with Unity on this on 08/29/2014, but no progress that I can see:
