Hi here is my issue:
I change window size by SetWindowPos (HWND from display), and then my display automaticaly change himself too.
I need this for smoothly resizing display with noframe flag.
Assume that we have display 100x100px, and the window has resized to 10 pixels more.
First I set display size from 100 to 150, and Second step is set size just a window to 110.
We have display 150 and window 110.
Third step, when I click up a mouse, I set display size to window size.
By this way, display resizing isn't called many times, only every 50 pixels. But like I said, display size change automaticaly to window size.
