After upgrading chromium to version 6.0.472.55 there started appearing ugly artifacts on the interface buttons. They appear after hovering mouse over them and disappear when the window loses or gains focus. I'm attaching a screenshot.

Please post steps to reproduce. Which browser theme are you using?
It turns out it wasn't a chromium bug. Actually a cairo update messed this up. The 1.10.0-r1 version of cairo fixed it.
