Viewport mouse issues

Hey I am having extreme “twitching” problems in the viewport everytime I rotate the camera, or move and object, or just interact with an object at all… I was wondering if anyone else had this problem or knew how to fix it. I have attached a video showing the problem I am having:

I am on Mac OSX 10.10 with the following hardware

Any help would be great, it does not make Blender unusable but very annoying.


Supply an example blend file for review.

You can see the transform values not changing as you move the object so something is incorrectly interferring with the movement.

Have you tried disabling auto keying
Have you tried deleting the existing location and rotation keyframes
Check for any constraints
Check for anything odd in the graph editor that may affect the keyframes
