anyone else experiencing this every so often? i'm still trying to find what's causing this problem. will randomly happen, often when using the new pages... ignore the 2 white boxes with black outlines, those are my own doing for privacy.

Sounds like your graphics card could be dying.

Try installing Mountain Lion (or whatever OS you were using prior to experiencing the issue) and see if the issue persists. If it does persist then something is dying, probably your graphics card since screen artifacts are a common side effect of a graphics card nearing it's final days. http://www.playtool.com/pages/artifacts/artifacts.html

I've periodically had that issue on both of my machines since the 10.8 days. I've only ever seen it when Mail is open; have you ever seen it without Mail running?
