Description Bogdan Nicula 2005-10-24 13:20:47 UTC 
Please describe the problem:
Please see
http://bugs.gnome.org/show_bug.cgi?id=319509
and
https://bugs.freedesktop.org/show_bug.cgi?id=4846

I replaced the GTK+ 2.8 implementation of gdk_window_clear_backing_rect to the one in 2.6 and both 
CPU times spent in the X server and my application dropped tremendously. The only Cairo functions 
that appear now above noise level are those related to Pango.

I consider this a regression from the 2.6 series. No matter how optimized the X server on Linux x86 is, I 
don't believe that there's no regression there as well.


Steps to reproduce:


Actual results:


Expected results:


Does this happen every time?

This doesn't happen for us, so please help us by  debugging the Cairo problem.
(You've already filed this against Cairo, so closing this bug)
