** Description changed:
- Using Ubuntu 16.04 LTS Beta release. Was using gnome-shell and using
- Chrome web browser when computer became unresponsive to any commands or
- mouse clicks. About 3-4 minutes later a crash report popped up on my
- screen. I clicked report and now I am reporting this as a new bug as I
- have never had this happen before on previous versions of Ubuntu. I was
- attempting to copy and save an image from Google Chrome when this
- happened.

+
+ Similar crash still happening, as per
+ https://errors.ubuntu.com/problem/fda12af21f79f7f1e23ab3cc830da47eca410baa
+
+ ----
+
+ [ Test case ]
+
+ Run xinput and figure device IDs for your mouse.
+ Run this evil script with 9 changed (be sure to change both) to your id:
+
+ for ((;;)) do xinput disable 9; echo Disabled; xinput enable 9; echo
+ Enabled; done
+
+ While the script runs, open some context menu in some program. It may require
a few clicks due to evil script enabling/disabling mouse.
+ This will sometimes crash GTK programs due to a mirror bug in GTK.
+
+ GNOME Shell should not crash
+
+ [ Regression potential ]
+
+ Devices might be not be properly recognized when plugged and unplugged
