Bug description:
[ Impact ]
Using Ubuntu 16.04 and 20.04 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
