Video corruption at random times.

My video goes all weird. It seems like it never happens while I’m at the pc where it would go from normal to weird. It’s like after the PC has been running. This never happened with Windows. Only OpenSuse. I don’t know how to describe it. So, I took a video of it. Here’s a link so you can see yourself what it does.

The only thing I can find to do to fix it is ctrl + alt + F key and then sudo shutdown -r now to reboot the pc.
