Bug#896700: gnome-session: after gnome startup process CLUTTER_BACKEND says x11, breaking clutter based applications

[Johannes Rohr]

Package: gnome-session
Version: 3.28.1-1
Severity: critical
Justification: breaks unrelated software

Please feel free to reassign as appropriate. Something during the gnome-session
startup process sets CLUTTER_BACKEND=x11

This breaks gnome-control-center:

(gnome-control-center:4903): Clutter-Gtk-ERROR **: 20:48:43.776: *** Unsupported backend.
Trace/Breakpoint ausgelöst

Probably breaks also other packages which use clutter.
