Comment 10 for bug 689741

I'm sorry, I don't have a natty system to test against, however you can do some
testing with owen's python testcase app, which I've attached.

Just change the SIZE = XX line and test, i.e. setting it to 12, creates a
12x12 grid, changing that to 48, creates a 48x48 grid and so on. You should
be able to get to a significantly larger grid and have it update at the correct
rate (1/sec) with the patched GTK+, especially on slower hardware, with less CPU
usage, than with the unpatched GK+ version, the effect may be harder to see on
the latest and greatest machines.

Subject: [Bug 689741] Re: libgtk2.0-0 performance problem due to unused cruft
from 10 years ago

Upstream commit that fix in their stable serie:

http://git.gnome.org/browse/gtk+/log/?h=gtk-2-24
http://git.gnome.org/browse/gtk+/commit/?h=gtk-2-24&id=c282958fb4bb25c736c682735002d15c50cb44d0

I've backported that to natty now, could you test the update and let we
know how much of the issue it solves or if the other gtkwidget change is
also required?

Upstream did that extra change in trunk:
http://git.gnome.org/browse/gtk+/commit/?id=b7fd6f1e8826589646e2b0e2d7a848fc2fab3ee3

Which will land in the next gtk3 update, that one is not in gtk2 yet
though.

If the fix works correctly we will consider stable updates for other
ubuntu series but it needs testing in natty before
