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. -- David J.

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 -- You received this bug notification because you are a direct subscriber of the bug. https://bugs.launchpad.net/bugs/689741 Title: libgtk2.0-0 performance problem due to unused cruft from 10 years ago ** Attachment added: "test.py" https://bugs.launchpad.net/bugs/689741/+attachment/1766710/+files/test.py -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gtk+2.0 in ubuntu. https://bugs.launchpad.net/bugs/689741 Title: libgtk2.0-0 performance problem due to unused cruft from 10 years ago -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
