Comment 7 for bug 331719

I've just tried using linux 2.6.29-rc6 and am still experiencing the problem.

Further, I can most easily reproduce the failure by having mode setting enabled on boot, with gdm starting up. I logging in to Gnome happens successfully but on rendering any new window, things lock up as described. I.e., starting an application, a popup window from a panel applet, but not the panel window itself, oddly.
