Text flakes on Win8 in DM

Project Member Reported by, Aug 15 2014

Issue description

DM flakes on text sometimes. A character substitution occurs or advances appear to be different. This seems to have started with advent DM, suggesting a threading issue. I sometimes see this when I run DM locally on Win8. It occurs on the Win8 bots sporadically but not the Win7 bots.

Not sure if this is related. I got this error running dm just now:

This will not show up on the buildbot page anymore.  Rather, it'll show up as different images on skiagold now.  We marked the bad images as negative in skiagold during the first triage Friday.

Still pretty problematic though. We will need to triage every random image the test generates.
