Confirmed this to fail on the following hardware: - SPARK, GIADA, MACBOOK_AIR_OSX, MACBOOK_AIR_WIN, MACBOOK_PRO_OSX, MACBOOK_PRO_WIN, MACMINI, MACPRO, NEXUS-4, NEXUS-5, NEXUS-10, SURFACE, WINDBOX, HASWELL, HPOMEN (All tested configurations, so looks like hardware independent) On MACBOOK_PRO_OSX, the test even crashed, see https://bugzilla.mozilla.org/show_bug.cgi?id=1178601 for details. See https://bugzilla.mozilla.org/show_bug.cgi?id=1178601 for hardware configuration details of these systems.

The d3d9 and d3d11 backend are now passing on Windows 10 with HD 4000.

Ubuntu 16.04 also working with HD 5000. 50.0a1 (2016-06-09)
