After upgrading to 7.10 gutsy, gnome-panel hangs very frequently,
chewing up cpu. It seems to happen when a new window is created, causing
some bad comm loop to happen - possibly with window list applet? That
too started behaving strangely, resizing frequently without any new
windows being created. I'm using sawfish window manager, on a thinkpad
t60 with Intel 945 graphics card.
System information:
gnome-panel - 1:2.20.1-0ubuntu1
sawfish - 1:1.3+svn4194-1
xserver.xorg - 1:7.2-5ubuntu13
Some output from strace on gnome-panel:
