I would like to disable displaying of the content of the window when resizing, is it possible? The problem is that when I'm resizing my window the controls redraw on correct positions but it doesn't look good because it's not done fluently.

EDIT: I would like a code that would manage the following scenario:

1. I click on the corner of window
2. Now only the border of window is visible - the middle part is transparent
3. I set the size of the window by mouse
4. I release the mouse button and the middle part of the window will appear
