Also reported to the unofficial-webapp-todo developer (mxarc#1) and unofficial-webapp-office developer as well (sirredbeard#28).

Just as an example, using Mail, attempted form command line using QT_DEBUG_PLUGINS=1:

$ QT_DEBUG_PLUGINS=1 snap run icloud-for-linux.mail

Looks like https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1424 broke X11 for snaps :/

Upstream bug: https://gitlab.gnome.org/GNOME/mutter/-/issues/1454

@eeickmeyer could you try the latest snap and see if this issue is now resolved? Thanks!

Nope. For me, instead of crashing, it's just ignoring the QT_QPA_PLATFORM variable.

Nope. For me, instead of crashing, it's just ignoring the QT_QPA_PLATFORM variable. Can you add the Wayland plug again to see if it works now?

[MarcusTomlinson]

Could you try v0.12 - Run snap refresh icloud-for-linux.
