Subject: [PATCH] Wayland: Fix missing damage event on window show

By definition a hidden window on Wayland does not have valid framebuffer
contents.

This adds a window damage (refresh) event when a window is shown, to
request an initial frame for the now visible window.

(cherry picked from commit 25c521cbe5acd58641740db5063d33fb51eeb882)
