I've been using my DL adapter on my Mac for a few months without too many issues. Today I noticed a lot of CPU being used by the 'WindowServer' process, which is abnormal. I had a single Firefox 4 window open on my DL display with a dozen or so tabs. Once I move this window off the DL display or just minimize it, the CPU usage for the WindowServer process drops from 50+% to around 2%.

Even a single tab window with the Google home page on it shows similar CPU usage. I'm going to roll back to Firefox 3.6, but I wanted to throw this out and see if anyone had similar issues.
