Commit d714a94d9 added support for stable xdg-shell surfaces while preserving old unstable zxdg-shell v6 ones, but committed a mistake in checking for both in the xdg_exporter.export error condition paths. We want to check that the surface is neither of both. https://gitlab.gnome.org/GNOME/mutter/issues/63 Closes: #63
