TL;DR version: Window open and close animations hang and the computer eventually 'locks up'.
Full story: I've been trying to get Mountain Lion up and running on my laptop (Lenovo Thinkpad T61) which has been unable to run Os X due to it having a nVIDIA Quadro NVS 140M GPU. The previous versions of Os X lacked support for it so I gave up on it. However, when I gave 10.8.2 a try I found that it natively supported the GPU with acceleration and all. However, it has been giving me a strange issue that I haven't been able to troubleshoot.
In both the installer and operating system I often have a "beach ball" (not spinning) as a cursor, rarely does it turn to an arrow and the only time does it spin is when a program is "not responding" and only when the cursor is over that non-responsive window. However, the real issue lies in the way windows open and close, as well as icon animation. If I open "About this Mac" from the Apple menu the window will fade in correctly however, If I were to close it or click "More info" there is a 95% chance that it will stop mid-fade and remain on the screen overlaying the "System Information" window. The same happens any other window that fades in, sometimes I'll get a tiny, pre-fade in window in the center of my desktop that is interactive, but it's super small and I can't read anything on it. The same goes for icons if there is any animation it will freeze and leave a residual icon. See the screen shot for an example. Eventually, enough windows will start doing this that I can't use the computer. Either it will stop working completely (as in it will become non-responsive) or no other windows will open (such as, opening Safari won't open a window). I have to reboot to "fix it".
I have a DSDT installed, but I haven't edited it. And, I've tried other graphics related KEXTs (even rolled back to 10.8.0 thinking 10.8.2's KEXTs were causing it), however since 10.8 is the first version to support this video card none of them worked. I'm not having much luck with anything else.
If anyone has had similar experiences or can think of another way towards a solution, I'm all ears / eyes.
