flashy screen problem?

This happens sometimes after a bit of playing...

Flashes in and out of that image and normal screen and you have to alt + tab out and in before you can play again... gets really annoying sometimes..

This is weird, so your game automatically minimized and when you re-open this everything on your UI is missing? Have you tried playing windowed mode?

Not exactly... basically sometimes when i'm playing the UI starts flashing in and out of the screen, i can still see the map and stuff but it just like goes forward and back i.e if i threw a star and it happened then it'd just go slightly forward then back etc.. the only way i can fix this is by switching out and in again and thats really annoying when its a boss run etc...
