vo_x11: reduce flickering on playlist navigation 

The delay between call to .resize, which cleared the buffer, and
actually rendering the first video frame, was significant, resulting in
short flicker on navigation and resizing. This was especially visible
when zooming and navigating between images.

Now the clearing is scheduled to happen just before the rendering, which
looks to be good enough even without double buffering.
