I came across this bug a few weeks ago using Firefox 3.6: sometimes, when a notification should appear, the space for the bar is carved out at the top of the screen but doesn't get filled with anything. I couldn't repro it, and it eventually stopped happening, so I chalked it up to random inexplicable weirdness and let it go. Then, yesterday, using Chrome 5.0, I saw this in the middle of editing a question (freehand circle/text added after the fact, of course):
Has anyone else encountered this blank notification message behavior? I still can't figure out how to repro it, so I need some help figuring out what's going on.
(I would also accept "'We are aware of this issue and are actively working on a fix.' -Valued Associate ♦.")
Awareness bump for tangentially related bug: at the time, I barely noticed the notification area — the white just blends in — and figured it was probably a new answer that wouldn't interfere with my edit. Afterwards, I found out that some comment magic happens automatically with question closures, and I ran into a known bug; credit to Lance's comment on the original question.
