[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[DavidJB (davidjb)]

For me, this has happened twice when typing Control-N within Firefox, causing Xorg to crash. Both times were days apart, and both had occurred shortly after a resume from suspend on my MacbookPro10,2. I can't replicate specific circumstances to trigger this bug today mind you.

[Xavier (xavier-monset)]

For me, it'appear when I click on launcher. may be 5 or 6 times a day. Mainly when there more than one window for an app.

[DavidJB (davidjb)]

About an hour or two after resuming from suspend, pressing Control-N in Firefox caused this to reoccur. Trying the key combo again now is fine; opening 5 more windows without an Xorg crash. Not sure if it's a cause, as Xavier says, by number of windows, but my Firefox typically has 5 or more windows open, a video playing in VLC and a terminal.

I haven't see the issue occur with anything but Control-N so for me, my workaround is avoiding that key combo and we'll see if the issue comes up again when windows open.

[Xavier (xavier-monset)]

and just now : A crash while I was trying to get a new tab on chrome... ( not with keyboard as David but by clicking on the icon)

[aldebx (aldebx)]

Disable window animations in Compiz reduces the frequency of the crashes. Use compizconfig-settings-manager for this tweak (sudo apt-get install compizconfig-settings-manager)

I didn't run into this issue for several days after upgrading to kernel 4.3 from http://kernel.ubuntu.com/~kernel-ppa/mainline/
