Jittery Blender controls with Logitech Mouse

Hi,

I’m using Blender on a MacBook Pro running OS X 10.9.3 and I’ve never experienced problems like this. I have recently bought a new mouse, a Logitech M510 and am now experiencing very jittery controls when using Blender to a point where it’s completely unusable.

Here’s a quick recording of the problem: http://gfycat.com/MiserableGiantDove

Thanks for any tips in advance! :slight_smile:

In case anyone stumbles across this in the future:

It’s caused by a bug in the software SmoothMouse for OSX. The easy fix for this at the moment is to disable Continuous Grab in the Blender User Preferences > Input.
