bug 1047613 causes occasional black flashes when populating the results-pane of the awesomebar with unifiedcomplete.

After disabling OMTC, the flashes are gone.

The numbers in the filenames of the attachments indicate the timecode of the black flashes.

I guess when bug 1047613 is fixed, the flashes will be gone too.
I filed this bug just in case there's more to it.

Using a debug-build, the log gets spammed with
>[GFX3]: Invalid draw target type specified.
while entering text into the awesomebar.
