[Development] Help required with QTBUG-56932

[Lisandro Damián Nicanor Pérez Meyer]

On Debian we've got affected by this bug which renders KDE/sddm
unusable. Strange enough it does not happens in Qt's CI but it does on
our tests... and users :-P

The bug has a small test case and a possible commit that created the issue.

Thanks!
