Bug Description
Binary package hint: xchat
I'm on a fairly slow machine, but it's generally perfectly snappy.
Experienced with nouveau from edgers and with restricted nvidia driver.
With xchat open but minimized, idle compiz cpu usage is around 2% to 5%.
With xchat restored, with an idle channel visible, compiz cpu usage goes to 40%, and other desktop operations (dragging windows, working in other applications) becomes noticeably jittery / laggy.
Minimizing xchat again brings compiz cpu usage back down to idle.
This occurs on a freshly restarted compiz and xchat process. (via closing and quiting xchat and "compiz --replace")
Running
> strace -p $(pidof compiz) -o /tmp/strace-
with xchat minimized and visible (the output of which is attached) shows both compiz and xchat with an order of magnitude more activity while visible (again with only an idle channel visible).
