Weird flickering during SHFB initialization

Apr 2, 2014 at 9:12 AM
Hi Eric,
I noticed something weird when I started SHFB. I had a notepad window with some text open on another screen and then started the GUI. While the GUI was initializing, the contents of the notepad window flickered constantly. (Win 8.1 64bit)
One hint I can give, but maybe it's not associated: Years ago I noticed flickering in other applications when my code called Win32 APIs that needed a HWND window handle and my code had a null value for this parameter.

I was able to duplicate this. It does it when the main form is resized as well if there are tabbed documents or the properties window open. If the tabs are closed, it'll do it when the window starts to resize but then stops and won't flicker anymore after that until properties window or tabbed documents are opened again. As such, I'm guessing it has to do with something that the dock panel suite is doing. Since it's just a minor annoyance and is not in the SHFB code base, it's not something I'm going to try and look into further.
