Problems (?) with 1080p

[711]

Hey!

First and foremost, I have an AMD 960T with 8GB of RAM and a R9 vga.

My host is Windows 10 64 and the guest is 7 64 also.

After installing the guest additions I could run the VM in 1080P no problem by either dragging the screen or hitting full screen but if/when I try to run a fullscreen app it only shows a tiny square surrounded by black boarders.

CLueless on what to do next.

Any help would come in handy, thanks!
