The failure did not occur on any of the following: GIADA, MACBOOK_AIR_OSX, MACBOOK_AIR_WIN, MACBOOK_PRO_OSX, MACBOOK_PRO_WIN, MACMINI, MACPRO, SURFACE, WINDBOX, HASWELL, HPOMEN (see https://bugzilla.mozilla.org/show_bug.cgi?id=1178601 for hardware configuration details of these systems), so this looks like it affects only Adreno and Mali devices?
