When I changed my desktop from x11 to wayland (ie logout and login again into wayland), I found out that insync was not working (by looking at the icon tray). When I run command insync start --qt-qpa-platform=xcb --no-daemon, it produced no error. It also produced no error when I changed the start to show. BUT, if i reboot my machine and straight into wayland session, it worked.
And can you explain the use of --qt-qpa-platform=wayland/wayland-egl etc2…?
Thanks.
This is my system:
KDE neon User Edition 5.19 x86_64
