Description Dan Ziemba 2013-10-13 02:44:03 UTC 
When I attempt the drag one of the columns in the process list to a different position, most of the time it will freeze after moving a small distance.  At this point, the mouse still moves, the clock still ticks, and the ripple in the upper left still appears, but the overview won't open and nothing can actually be clicked.  Keyboard interaction also doesn't work.  Switching to a VT and sending SIGKILL to gnome-shell restarts the shell but it remains in the same condition.  Killing gnome-system-monitor does not help.  I was able to reproduce this bug about 7 out of 8 times when trying to drag the memory column to the left.  Let me know if there are any logs or debugging output that I can provide.  

Additional info:
OS: Arch Linux x86_64 running as Xen 4.3 dom0
Processor: Intel i7-3770

Comment 1 Stefano Facchini 2013-10-13 10:51:02 UTC 
Does it happens only with System Monitor or in general when dragging columns of a GtkTreeView? Probably a duplicate of bug 705176 (or closely related)
Comment 2 Dan Ziemba 2013-10-14 02:27:23 UTC 
Looks like it probably is a duplicate.  I can't tell if it happens with other applications since I can't actually find one using the draggable columns, even in gtk3-demo.  Is there a specific program you know of that I can test?
Comment 3 Robert Roth 2013-11-05 21:35:16 UTC 
@Dan Ziemba: I have added a compilable example app in the other bug, https://bugzilla.gnome.org/attachment.cgi?id=258913.

Could you please download and test if that also freezes your gnome-shell? I have tried and it did, so I guess you're seeing the same issue, but please confirm, so we can mark this a duplicate.
Comment 4 Dan Ziemba 2013-11-06 03:56:16 UTC 
I can confirm that that does freeze gnome shell 3.10.1 when I drag one of the columns.  Switching to a VT and killing it unfreezes the shell.
