Summary: [Webkit] Chrome scrolling up causes graphic bug with editor borders.Scrolling up causes graphic bug with editor borders.

Apparently this happens in IE9 as well seemingly at completely random times. The issue might be with my computer if nobody can reproduce but this is getting very strange. Attaching image in a moment.

I was able to reproduce this issue in IE9, Chrome and with Moono skin only.

IE9 - All I had to do is open demo page with standard mode, scroll editor a little bit down, scroll the page a little bit down (optional) and then scroll editor again.
Sometimes only scrolling down the editor slowly is enough (See IE9 video).
I was able to reproduce this on my local computer. Besides grey lines (which are not that easy to reproduce as in demo page) I have also got wrongly rendered text (See ie9.png).

Chrome - All I had to do is open demo page with standard mode, scroll editor down with mouse, next scroll it up clicking scrollbar arrow. Please see Chrome video.

This is a Chrome issue, which seems to have been fixed. So, either this is a regression or it didn't land on any public Chrome release still.

The good news is that this bug has been fixed on Google Canary, so we should have a public fix soon.

In fact, this is one of those weird bugs that should be fixed in the browser itself.

It's great to see that this has been fixed with Chrome 24.
