I'm usually not one to make a new thread but this problem is starting to bug me. Snow Leopard (10.6.2) has been running reasonably for the past few months short a few graphical issues. They tend to happen on both my iMac Core Duo and MacBook (Late 2007). I suspected the half hearted video drivers for both older Macs. Recently it started getting worse on the MacBook, especially in Finder, that can be resolved by logging out. Eventually it'll start happening again though. Moving a window over the garbled parts doesn't fix it. It just showed up in the Cmd + Tab switcher as well. I logged out again and that fixed it for now. How is taking this to the mothership going to end up?
