P: Zoom/Pan and selection tools freaking out

Hello!

I did some searching on the forum to see if anyone else is having similar issues and haven't been able to find anything. 

When I try to zoom or pan around an image the screen freaks out and seems to be flickering back and forth between incredibly zoomed in or out. It's almost impossible to work with and the only thing that seems to resolve it is restarting the program and hoping to get a decent amount of work done before it happens again.

It also seems to be affecting the selection tools, as clicking once with the lasso creates a wild spiderweb of a selection as if the cursor is being dragged all over the screen. This also happens with quick selection, and as far as I can tell any other selection tools. I've attached a screenshot of what happens when I click once with the lasso tool.

I've tried this with "Use Graphics Processor" checked on and off and there's no difference. I also tried enabling and disabling scrubby zoom and animated zoom. 

Anybody have any idea what's going on?

Thanks!

Tristan
