Major Graphics Glitches in 9.5.3

Just up’d to 9.5.3 and now can’t resize anything. Window sizing is kind of frozen in some projects, “auto maximizes” to off-the-screen sizes, does a “flashing white / glitch / won’t move” thing when moving prject window. tool bars and racks “hidden” and unaccessable in mixer #1, but not in #2 or #3…called it quits at that point to see if this is a know issue…

This is in Win7pro-64 / latest nvidia driver for gtx580 card

Okay, so I thought i had the latest video driver, but there was a new one available. Seems to be working better so far.
