Details

During Firefox startup on Windows 7, I first see a whole sheet of glass and only afterwards the contents of the window are painted. We should not make the window visible before the contents are rendered for the first time.

This began a few days ago. It could also be a Widget bug, but I'm filing it in Layout because I suspect bug 598482. I can bisect this, but won't be able to do it today.
Gavin says that he sees this problem on OS X too

Judging this is very hard and subjective on optimized builds on a fast machine, but using mozregression I did get the following range:
http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=21c84409902e&tochange=047c8ba7d2e4

I'll probably need to bisect it with debug builds to be certain that is the right range
I got a profile where it's much easier to observe this for me (tried now with my default profile with some app tabs on SS), and I got a different range:
http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=5a446202be5f&tochange=cf8c9f9aeefc

I'm much more confident in this range now.
Bug 716334, which seems to be the same as this one, blames the regression on bug 618770 (which is in your range), but I don't know whether that has been confirmed by hg bisecting.
Indeed, I finished bisecting

$ hg bisect -g

I saw "a big sheet of glass" right after updating to Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:16.0) Gecko/16.0 Firefox/16.0a1 ID:20120605030522

Should I reopen this one or file a new bug?
