balena etcher generates gtk warnings

run etcher get warnings

$ /opt/balenaEtcher/balena-etcher-electron
ready-to-show: 14757.893ms
Gtk-Message: 20:40:04.408: GtkDialog mapped without a transient parent. This is discouraged.


Etcher uses electron to handle it’s UI, and I believe this is a known long-running issue:
Etcher should still work correctly even with this warning.

Best regards,
