Description Joanmarie Diggs (IRC: joanie) 2013-10-18 16:54:10 UTC 
Steps to reproduce:
1. Start gnome-shell-wayland
2. Launch gnome-shell's magnifier from the Accessibility Menu
3. Launch gedit using the wayland backend
4. Begin typing in gedit

Expected results: The session would not segfault.
Actual results: The session reliably segfaults.

Notes:
1. If gedit is not launched using the Wayland backend, the bug does not occur.
2. Disabling the magnifier's caret tracking does not prevent the bug.

It has a problem with gedit at the moment when it is not under wayland as well.

Is this not a mutter-wayland or cogl bug? I suspect these.

Joanie, is this still a problem with the upcoming Fedora 21/GNOME 3.14?

Thanks for the ping Bastien. I'm not seeing that crash in Fedora 21/GNOME 3.14.
