Environment: Win 7 64-bit
I have the same results as above on Nightly 39.0a1 2015-02-25 and Google Chrome Version 40.0.2214.115 m.

[Jukka Jylänki]

This was tested to fail on the following devices:
 - SPARK, MACBOOK_AIR_WIN, MACBOOK_PRO_WIN, NEXUS-4, NEXUS-5, SURFACE, WINDBOX, HASWELL, HPOMEN

The failure did not occur on the following devices:
 - GIADA, MACBOOK_AIR_OSX, MACBOOK_PRO_OSX, MACMINI, MACPRO, NEXUS-10

See https://bugzilla.mozilla.org/show_bug.cgi?id=1178601 for hardware configuration details of these systems.
