Weird Render Globals window error
 

Just wondering if anyone else has run into this...

I have a project set up to render out at 1080p. Whenever I open the render settings, the window flashes and the "image size" settings revert to 640x480. Dumped the prefs, no love. Also, noticing that instead of the just showing tabs in the render settings window associated with the engine I'm running (in this case MR), I'm getting tabs appearing in a grouping I've never seen before - Common, Maya Software, Maya Hardware... etc. (see image).

I'm running osx 10.8 with a Quadro4000, 2 Apple 27" LED displays and a Cintiq 22HD. The machine is new. Been noticing some glitchyness in After Effects as well - when I stop a preview from playing back, all the tabs seem to bounce around for a second before returning to normal. I'm thinking this is probably a graphics card issue but hopefully someone out there has seen this and has a quick fix.

Thanks!
