Build mode cursor glitches

I’ve been using a build tool while building in build mode, whether it be in studio, or just the non studio version, and I get a constant problem with my mouse. Whenever I try to drag something like a resize point, or simply move my cursor, it starts spazzing out and moving back and forth without my control, it makes building virtually impossible.

Has anyone else experienced this problem, or know how to fix it?

What type of operating system do you use?

OSX

Can confirm on OS X Yosemite. It doesn’t happen all of the time, but it usually goes away when I turn down my graphics settings.

My mouse in play solo does this always. But I’m on Windows 10 and I guess that’s not officially supported yet.
