Ive noticed this on on ocasion when the extents of your model has be exceeded.
Check that your not getting this error, and also that your Project base point isnt too far away from the centre of your project.
This type of issue is usualy realted to graphic cards.
Here are some things to try:
1. Update your graphic card
2. Make sure you have the latest update for Revit
3. Turn off Hardware Accelaration - Go to the big "R" on the top left>Options>Graphics
4. Use Revit on the primary monitor , if you are using dual monitor.
Hope that helps!
