Looking at the screenshots from the test logs such as <https://tbpl.mozilla.org/php/getParsedLog.php?id=26870396&tree=Date#error0>, I see that these test VMs are running at 1024x768. Our reftest framework requires a minimum size of 1000x800, so the screen is not tall enough on these machines. This will probably break a bunch of tests which are depending on the minimum resolution (and it's what causes the "REFTEST TEST-UNEXPECTED-FAIL | WARNING: USE_WIDGET_LAYERS disabled" at the beginning of every reftest.) It may not be worth looking into the test failures on Date until this is fixed.

hmm, I'm guessing this comes from how we initialize the RDP session. Hopefully I can set the geometry and colour depth.

They _should_ be running 1280x1024 now.

great success!
