Can you ask for the profiles to be done with "Firefox Graphics" preset?

Jeff, the user claims that they used the Firefox Graphics preset, and if you look at the "Threads Filter" I see WrWorker there. Is there a bug in the profiler?

I can't reproduce this on win8.1 with the same driver on a HD Graphics 4000 (0x0162)
