These are failing on WK1 Mavericks about 40% of the time.

Dean added expectations for these tests, but the syntax was not correct (it should be Failure, not Fail). Also, no expectations should ever be in platform/mac-mavericks/TestExpectations, it's just a wrong place for those. I think that these should be in platform/mac-wk1.

Strangely, this only happens on one of the two bots serving this queue - it always happens on s-bot-138, and never on s-bot-137. I tried rebooting s-bot-138, but that didn't help.

One difference between s-bot-137 and s-bot-138 is that the latter doesn't have a display dongle. I don't know if this would be the cause for something like this though.

I changed display preferences from "scaled" to "best for this display", let's see if that changes anything.
Comment 4 Alexey Proskuryakov 2014-12-07 00:28:59 PST 
Looks like that helped!
Comment 5 Alexey Proskuryakov 2014-12-07 10:44:06 PST 
I'll move things out of the wrong TestExpectations file.
