World of Warplanes calls SetWindowLong(window, GWL_STYLE, WS_POPUP)
before calling reset, effectively hiding the window. It does not call
SetWindowPos(SWP_FRAMECHANGED), so the effect isn't visible and the
game displays fine after the reset. However, after the next mouse
click WINPOS_WindowFromPoint skips the window because it doesn't have
WS_VISIBLE and returns the desktop window. This in turn triggers a
focus loss and d3d9 minimizes the game.
