Opening a chat window makes scrolling really bad. It feels like we are repainting the entire page on scroll. It feels like the buddy list iframe is causing problems.
This problem shows up really badly on linux. But even on OS X, scrolling seems to get quite a bit slower.
But the scrolling performance degrades visibly even without the buddy list iframe, having that open just makes things much worse.

Yes, we're repainting the whole window when the chat window is open. It's probably something to do with the region complexity limiter. I'll look into it.

Per Jeff, reopening.  Opening a couple of gtalk internal-windows noticably degrades my gmail scrolling experience.

Intel graphics, D2D doesn't seem to make a difference.

With the latest hourly builds and retained layers enabled there seems to be no degradation of scrolling performance. This bug seems fixed.
jeff, do you agree?
