Windows Vista 32 bit
Worked: in 2.73, 2.74 (optional)
NOT working in 2.76 new.
Problem made each time pressing ALT + F11 on Windows Vista.
Exact steps for others to reproduce the error
Just open fresh Blender 2.76 and press, ALT + F11 2x.
(first time to full screen all is ok, second time is NOT all ok)
I added screenshot for you to see "refresh problem" I get.
Regards, to all. :)
