The latest Chromium does not freeze on me, but I'm experiencing the occasional "whitescreen". The main window of the browser is empty, but everything appears to work, links load (according to tab information), menus work. There's just nothing displayed in the browser's main screen. Restarting Chromium doesn't work, restarting X doesn't work. I have to reboot. Meanwhile, Firefox and other apps have no problem, though VLC seems to show interface problems as well. It appears to affect something in the underlying OS, not X.
