This commit to gtk-3-22 seems to expose a bug where Totem in maximized mode
causes the video to be offset from the origin (see attached screenshot, the
problem is worse in full-screen).
It seems as if the initial call to wl_subsurface_set_position () is done with
an incorrect initial position that would have been corrected at a later call,
but since the idempotency check was added, this is no longer the case and the
subsurface is left at the incorrect initial position.</pre>
