Title: Set window Background to black

The background was being set to transparent, for example on wayland you couldn't see the window if only the background was set with an alpha value of 0 . This patch sets the clear color of tests and examples to black (and some to a transparent black). It also removes the first frame that was being drawn when a window is created avoiding a initial blink.
