Bug#1064335: mutter-common: xwayland apps ignore scaling settings

[Austin Pringle]

This bug also appears to break window titles and window decorations
under xwayland as well; now, server-side window controls no longer
respect user preference for positioning, ie,  they always render on the
left of the titlebar, even if the user has preferences set for them to
be on the right, and it always draws minimize, maximize, and close, even
if the user preferences only want the "close" button to be drawn.

This might actually be https://bugs.debian.org/1064438 which can be
fixed by installing gsettings-desktop-schemas from Unstable.

Thank you,
