Here is the recording on how it behaves (Win 8.1):

Is this happening on the unchanged FileDialog project?

I am also running Win 8.1 and I'm not seeing that behaviour. Could it be caused by a shell extension you have installed?

[tmedanovic]

Good point, I did change some code while debugging, but it trivial.
Nevertheless I will try with clean one.

Well I have some extensions like:
Git, Java, LibreOffice, Notepad++, WinMerge, AVG, although most of them are context menu extensions (don't know if it matters)

I will try it on my laptop, clean win 8.1 intallation, and postback.

I tried it on my laptop, as I said, clean installation of Win 8.1,
only 3 apps are installed: BitTorrent, 7Zip, Chrome and with cleanly built solution.
Same thing happens.

Strange, it really doesn't seem to happen here - I wonder if it could be related to region? I am using a UK version of Win 8.1. What are you using?

[tmedanovic]

That was my first thought,
I tried changing Formats, Location, Keyboard layout, System locale (restarting after) to UK, I had Croatia (Croatian), but still same thing happens.

These two windows installations didn't came from same iso.
One of them was downloaded from MSDNAA, I'm not sure I understand what you mean by "UK version of Win 8.1", language?

Believe I'm seeing something similar on Windows 7 and Windows 10 systems. It seems to be triggered by Refreshes tripped by SHCNE.UPDATEDIR notifications that are caused by Windows updating things like the Quick Access list with Desktop as parent or Recent lists with parent shell///AppData/Microsoft/Windows.
Trying to figure out how to suppress ones that can't affect the folders currently open or ? Wondering if there's some sort of nesting going on because sometimes my app goes Not Responding for minutes while I watch Shell.ShellTreeView.SetNodeImage be called for every folder down from the Desktop I believe multiple times.

Checking now to see if I'm running the latest version of Gong Shell...
