Wayland not supported

[stshine]

On wayland compositor no window get displayed when the program runs.
I think gtk-layer-shell can be used for this.

Does setting GDK_BACKEND=x11 (when running dlauncher, not dlauncher-toggle) make it work? This just makes it run under xwayland, and might not be a good solution but it is mostly temporary until I can find a way to implement it correctly.

I guess it will work, but I don't have x server installed.
Whatever, no hurry :)

if you want a suggestion, using the wayland wlr-layer-shell protocol is a good idea for making launchers/bars. Here's a gtk library that does the bridging: gtk-layer-shell (rust).

The only problem is Mutter does not support it, but one can use it via the X11 backend instead.
