Description of problem:

Connecting with rdesktop to a Windows 7 box that has GoToMeeting running inside it with a remote participant's screen shared (or starting up GoToMeeting from within the rdesktop session) causes gnome-shell window management to hang.  I cannot close the rdesktop window, and I sporadically cannot click on other widgets such as the clock/calendar, logout menu, or Activities.  I am unable to enter overview mode with the keyboard Super key, and neither am I able to use Alt-Tab, Ctrl-Alt-Arrow keys to switch to a different application or desktop.  The only thing I can do is go to another text VC with Ctrl-Alt-F3, log in, and killall rdesktop.  Returning to the desktop then restores control.  It seems like a focus grabbing problem, but I'm not sure, because sometimes I CAN click e.g. the clock/calendar widget, but still can't do any of the other actions.  Typing Super-M sometimes allows me to be able to access the clock/calendar, but doesn't seem to unstick anything else.  If I right-click the rdesktop icon in the top bar, a Quit menu appears, but clicking on it does nothing and does not even dismiss the menu.  Then the menu gets stuck there.

Version-Release number of selected component (if applicable):
gnome-settings-daemon-3.16.3-1.fc22.x86_64
gnome-shell-3.16.4-1.fc22.x86_64
kernel-4.4.3-201.fc22.x86_64
mutter-3.16.4-1.fc22.x86_64
rdesktop-1.8.3-1.fc22.x86_64
xorg-x11-drv-ati-7.5.0-3.fc22.x86_64

How reproducible:
Every week for the last 2 or 3 weeks when I have a GoToMeeting :-)

Steps to Reproduce:
1. rdesktop windows7.box
2. Start GoToMeeting
3. Maybe maximize GoToMeeting once a participant has shared their screen

Actual results:
As describe above

Expected results:
No hang
