I don't know the associated impact of those; if they're *just* a warning with no other impact, then perhaps. > As for gnome-boxes, can you reproduce the problem with 3.21.3 from > unstable?

However, it seems like a compatibility issue if upgrading to a new libgtk-3-0 with the same SONAME breaks applications that worked with a previous version. Other than rare circumstances like "application doing something always clearly documented as broken and old versions let them get away with it", which might *occasionally* be justifiable if it doesn't cause significant breakage in practice, generally that kind of compatibility issue seems like a bug in the library, not the application. > I think it would be best if you file this issue upstream at the > gnome-boxes bug tracker > https://bugzilla.gnome.org/enter_bug.cgi?product=gnome-boxes Before reporting it there, I'd need to confirm that 1) the bug still appears with gnome-boxes 3.21.3 and 2) the bug actually lies in gnome-boxes rather than in libgtk-3-0.
