Yosemite Graphics Corruption

[Apples555]

Ever since I upgraded to Yosemite, I've been experiencing minor graphics corruptions like this:

As can be seen, my searches turned this up as a common issue for 15-inch MacBook Pros with their switching GPUs, but my mid-2010 13" MacBook Pro has a single integrated Geforce 320M.

Has anyone experienced anything like this on their MBP? This didn't occur in previous versions of OS X and doesn't occur in bootcamped Windows.

Is that chrome? maybe just a chrome issue. not seen any problems on safari or any other app. using late 2011 macbook pro on discrete or integrated video card.

It's Firefox, but it happens everywhere, Finder etc.

On Windows, sometimes the entire system halts (the same quarter of a second of audio looping) for about 3 or 4 seconds, then everything returns to normal. Sometimes Windows gives a nvlddmkm error after this, as Windows thought the graphics card had temporarily stopped responding due to timeout.

Apple extended diagnostics check out fine. What the heck?
