vlc or movie player fullscreen issue

Hi...
I'm having this problem here that I can't seem to watch any movies properly in fullscreen using either vlc or movie player. I can watch them in small screen mode without any problem but when I go in fullscreen I get this scatter-type images..
any help would be greatly appreciated.

try this

open vlc, settings>preferences>output modules and change video output module from default to X11.

still same problem.thx anyway
