Screen problems.

Hello there.

I've recently bought a new gaming PC which i bulit myself.
I've added Zorin as the OS.

I have this problem in which when zorin loads and sends me to the desktop it bugs out.
It's hard to describe but I'll do my best.

The screen splits into 4 uneven segments, and only goes to normal if i hover over the "start" or "Zorin/ Z" button in the lower left corner.

If i click the "Start" buttom the normal Window? will pop up showing all the options such as Wine, settings, Etc.
But if i move my cursor from the "start" button into the window it bugs out and the whole window disappears. >.<

After which if i move my cursor over the now empty space the buttons will then appear after i hover over them, but only if they're a button.

I hope that made sense to someone. If now tell me and I'll do my best to re-illiterate for you.
