Strange texture bug when full screen

Hi.

When I window'd my game, and put it back to full screen, the texture and stuff looked weird. I then restarted the game, but it kept looking weird. I tried to switch between full screen and window'd but still looks buggy :/ Only looks normal in window'd mode.

Took picture with phone, cuz screenshot wouldn't capture how weird it looks like:

 

The picture quality is fine, it literally looks like that.

 

Would wonder be quite a lot, as the computer is just a few month old. It used to happen when I went into window mode and afterwards entered full screen, and it usually fixed itself but this time it's just stuck like this :/. Could it be the resolution?

 

Judging from the picture it's save to say that you mean the half there half gone tree.

Hmm... What are your specs and what settings are you running the game at?
Cause, as Nadeox said, it might be your GPU overheating.
Just download MSI Afterburner and look at the GPU temp.
(then again, if it gets too hot it should just tuen itself off)

 

It's the overall. Everything just looks weird, picture captured it almost accurate. GPU is fine as I said, it happened when I went from full screen to window, and then back to full screen.

Edit: Fixed, it was the resolution C: Thx for the suggestions<3
