Question

Unfortunately that redraw bug is still there, I have made a little video for you.

Answer 1

It seems I can't upload that video here. So for the time being I will put it somewhere else. Is 4.6MB to big?

Answer 3

So the problem is the following:
If the thread is longer than the windown and you have typed in a math formula, the input field will jump up and down while typing...
Hope you can fix it. My system is:
Gentoo Linux, Kernel 2.6.36 with
Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.16) Gecko/20110329 Gentoo Firefox/3.6.16
Of the addons I think would interfere, only AdBlockPlus and NoScript where installed but AdBlockPlus was deactivated and NoScript allowed all scripts, as you can see from the icons in the status bar.

Answer 4

Nope, that issue is unfortunately universal. We're still looking at a good way to solve it; in particular, I'm still polishing bugs off a potential fix I've written.

Answer 5

Today's release should significantly improve/eradicate this problem. Let me know if you're still seeing issues!
