Comment 67 for bug 88815

Michel,

Luckily your debs installed without any dependency conflicts, and I can confirm
that after restarting X the sluggishness is no longer present. Apparently this
is an xcb issue after all.

I'll certainly help out with profiling, but due to my lack of experience with
sysprof and oprofile, I just need a little time to figure out how to use these
tools.

Can you clarify what you mean by server restart experiments? Do you mean using x11perf, or checking the minimizing/maximizing animations? If it's the latter, Will I just run "metacity&" in the failsafe terminal and then run firefox, then start minimizing and maximizing - and check that with the xcb-enabled libs and without?

Sorry for asking for clarification, it's just that x11perf takes a long time on my system. And I think you're right that it's a client-side problem, as when I use kwin in the GNOME environment instead of metacity, there's no slowness. Downgrading metacity didn't help, though.
