Status: RESOLVED WORKSFORME

(Core :: Graphics, defect)

Description

[Mark Reid [:mreid]]

Opening http://maps.google.ca in Nightly causes X to crash in Ubuntu 12.04 on a Lenovo x220.

Steps to reproduce:
- Start Firefox
- Go to google maps (link above)

Actual results:
Desktop environment hangs.  The mouse cursor is still alive, but nothing else responds.  Sometimes the system semi-recovers and prompts to submit a crash report to Ubuntu.

Expected results:
Should let me use google maps.

[    91.771] [mi] EQ overflow continuing.  100 events have been dropped.
