First time a swap chain is created an incorrect resolution can be
reported back by the driver as the window is still initializing. We
stretch the swap chain to cover to reduce a black line rendering in top
of the window (due to content flipping). Any subsequent frame will not
do stretching to reduce artifacts when resizing the window.
