The first edition of this question: VB.NET - RichtextBox Control for Syntax Highlighting? (Fast, custom keywords, colors etc.)

Seems like the question text is all prettified despite it's not formatted as all code.
Does not happen in the preview.

This is what I see:

I see only one edition of that question, and it is not prettified as a whole. Do you have a screenshot? Was it editing in the grace period? Are you certain you are not looking at a stale version, clicking edit loads the current version, which could have been fixed already. – Martijn Pieters Mar 28 '13 at 22:00
@MartijnPieters I see only one edition, too. I said "first edition" in case a second edition appears while I type. Attached a screenshot. – GSerg Mar 28 '13 at 22:02
What browser, what platform? That is not what I see. The For Each line is not broken into two lines, for example. – Martijn Pieters Mar 28 '13 at 22:03
@MartijnPieters IE8 on Windows7. If I forcefully reload the post, the correct layout momentarily appears and then prettify breaks the for and colors it all. As I said, this does not happen if I try to edit the post -- the preview looks as it should, which is the only reason I'm posting it as a bug despite it's IE8. – GSerg Mar 28 '13 at 22:09
That still could be a bug in IE8. It's a fragile beast, IE8. Sometimes things break, sometimes they do not. – Martijn Pieters Mar 28 '13 at 22:11

I'm not immediately sure what causes things to break (something to do with the manual <pre> blocks*), but you should turn off Compatibility Mode and things should be fine:

compatibility mode button

I've also edited the post to use Markdown code blocks, which seems to resolve the issue even in Compatibility Mode.

*They had unbalanced <code> tags inside and outside their <pre> tags, which throws IE 8 off. I'm on an iPad right now so I can't easily account for the difference in rendered versus preview, but its likely similar to the case on Blockquotes in a list break blockquotes after the list (which also involved unbalanced tags, but at the fault of the Markdown parser instead of the user)

IE wasn't in compatibility mode so I didn't have anything to turn off. – GSerg Mar 29 '13 at 8:42
Ah, hmm. I tested in IE 9, so I guess the rendering bug that was triggered in compatibility mode must be present in IE 8's normal mode. I'll see if I can find a machine with IE 8 to dig further. – Tim Stone Mar 29 '13 at 13:07

Marking as declined -- we don't support visual glitches for this version of IE.
