As we unflip after the flip Window no longer passes the pixel ownership test for the full Screen Pixmap, we can no longer utilize that Window to copy the contents back to the backing pixmap. To first flip means that the Window was originally backed by the Screen Pixmap and wholly covered the Pixmap, thus we need to copy the last frame contents to the Screen Pixmap when the flip chain is complete.
