Weird power window correction offset

Hey guys.

I'm having the strangest thing happen since the last two days - a power window correction does not correspond with the outline - it has this weird position and scale offset. Basically the correction is an about 40% version of the power window outline, and offset slightly right from the centre, on the inside. I did update my nvidia drivers a few days ago, but the same thing when switching to osx driver.

Any thoughts?

Issue resolved - using proxy mode caused any power windows to show up with offset.
