VLC media player only plays Halfscreen instead of full

Hey guys

I recently switched from ubuntu 8.04 to opensuse and I don’t regret it for a second.

This is something I need help with, I open up a video in vlc and it plays, whenever I activate full screen it doesn’t really go fullscreen but half screen?

I tried some stuff like different video output disabling compiz.
didn’t work

can somebody help me out?
