Description Sebastien Bacher 2005-12-09 04:17:06 UTC 
After upgrade xorg from 6.8.2 to 7.0rc3 on Ubuntu switching between workspaces
with GNOME is really slow (it takes like 1s to redraw the background).

As discussed on IRC setting "surface->buggy_repeat = TRUE" to
src/cairo-xlib-surface.c fixes the issue.

This file exposes the issue:
http://bugzilla.gnome.org/attachment.cgi?id=47915&action=view
(from http://bugzilla.gnome.org/show_bug.cgi?id=306216)

with a 252x252 pixmap resizing the window is smooth and fast, with a 253x253 one
it takes a lot of CPU and jump every 1-2s to go to the next position.
