Also, it happens on my laptop as well, so it's not just a mobile thing.
From Dragonwolf's post I think this might have to do with the anti doubleposting thing.
Well, every time it goes black the message at the bottom of the screen saying that you can't doublepost is there, so I'd assume that you're probably right.
EDIT: Well, I've seen more than just the text have problems, I'll post screenshots as soon as I get on my computer.
EDIT2: Well, I finally got the screenshots.
More things are affected, such as the insert table and insert image options, however these were the screenshots I took of the problem.
Does anyone else have these problems?
EDIT3: So,
@darthmorf, sorry for the mention but I haven't seen a response mentioning the current status of this issue, or if anyone saw what I added in earlier edits, so is it still being looked into?
