pystray icon doesn’t work inside snap.
Here my code, you can clone, do
snap install tray_1_....snap --dangerous --devmode , and
snap run tray , but it doesn’t work, doesn’t show the tray icon.
If you try to do
./tray.py it will work.
Am I missing something?
Some interface? connection? plug?
My OS host is Ubuntu 20.04
