Package: libcairo2
Version: 1.12.2-1
Severity: important

I'm creating this issue as a reference.

cairo: [nvidia-302] Slow chromium tab switching with cairo-1.12.0
https://bugs.freedesktop.org/49534

chromium: Slow tab switching
http://crbug.com/121624


Workaround 1:
# nvidia-settings -a InitialPixmapPlacement=0

Workaround 2:
Pinning package to 1.10.2-7.

Workaround 3:
Building recent libcairo with patch changing src/cairo-xlib-display.c
by setting display->buggy_gradients to be always TRUE.
http://forums.debian.net/viewtopic.php?f=6&t=80382
(Consider pinning it too, in case of future libcairo2 updates still
lacking the fix.)


Currently I'm successfully using the 3rd solution.
