Just a follow-up. According to the comment of Pierre-Loup A. Griffais at cairo: [nvidia-302] Slow chromium tab switching with cairo-1.12.0 https://bugs.freedesktop.org/49534
the issue should be resolved with the driver 304.30. Copy-pasting relevant part of debian changelog: - Fixed a problem where RENDER Glyphs operations would exhibit severe performance issues in certain cases, such as when used with gradients by Cairo and Chromium. It's not yet in unstable, but when it'll get there, I'll try to check this and confirm. Jindrich Makovicka already confirmed at the mentioned bugtracker that new driver fixes the problem. The issue affects a lot of people, thus I think that the best solution would be the new nvidia driver hitting wheezy before it'll be released as a stable. Regards. P.S.
