If you are using the Direct3D renderer, it might be glitching due to the difference between running actual Direct3D and running emulated Direct3D. I would try using the OpenGL renderer. That's how I get FH to run on Linux and Macs have better OpenGL support than emulated Direct3D support. You will need to manually change the renderer via the "ogre.cfg" file in the game folder though, since you have no cursor.
