Subject: [PATCH] lok: render the whole slide temporary (with bg and master
 content)

This changes the rendering of the main slide layer content to also
render the master page and the background. This is needed because
of the issue with the white background (instead of transaprent).

(cherry picked from commit 99f9d663a26da00bebd8595f1e0819ebc6c3e4f0)
