I'm on Ubuntu 18.0.1 and using Gnome + Wayland and the snap has been working OK till the last update (rev 1087)

Strange. Must be some changes in snapcraft. I didn't change the snap config or libraries for ages.

I updated it on KDE Neon (Ubuntu 16.04) and it started normally...

$ sudo snap refresh qownnotes 
qownnotes 18.08.8 from 'pbek' refreshed
$ qownnotes

Snaps are built on https://code.launchpad.net/~pbek/+snap/qownnotes, maybe they have to iron out some troubles with Ubuntu 18.04...

I've opened a topic in the snapcraft forum to see if someone has any ideas about what has changed: https://forum.snapcraft.io/t/problem-with-qownnotes-snap-wayland/7055

Yeah, I have it installed, but I'm getting the same error. I've also tried to refresh core to the candidate (2.35) but with no success.

Do you have some other snapped Qt apps that you could test?

Well, you're right @pbek : I'm one of the mantainers of musescore and updated the snap today (only the beta & edge channel) and now I get the same error that with Qownnotes.

Hey @pbek ! Do you want me to do a PR here to add the variable to not start in "Wayland mode" in the snapcraft file?

It just arrived and it still works on my KDE Neon (Ubuntu 16.04, X11) system.

@pachulo, how does it look for you on your system?
