Xorg crashed with SIGABRT - sna_put_image() with drawable=0x0

[Johan Thorén]

This bug has been haunting me for a couple of weeks now.

It happens only sometimes when I interact with tabs in Firefox or Chrome/Chromium (all three tested, both stable and beta), about 3-5 times per day.

What did I do before the crash:

Interacting with tabs, creating new on, closing existing or clicking on active to change focus.

What should happen:

The browser should follow with the appropriate action, such as starting a new tab, closing the one I clicked on or changing focus to the one I clicked on.

What does happen:

X shuts down and kicks me out to the lightdm login screen.

Is this Unity related:

No, the same problem exists within Awesome WM.

Extra information:

* Using 2 SSD disks with full disk encryption.
* Using SNA and TearFree options to have totally smooth video playback.

[Johan Thorén (kveras)]

The problem exists in 12.04 as well.

[Chris Wilson (ickle)]

I believe I've fixed up the likely cause. (NB TearFree is still experimental.)
