[BUG] error(zwlr_layer_surface_v1@41, 2, "layer_surface has never been configured")

[madonuko]

Running gtk4-layer-shell 0.2.0 on my computer under Wayfire causes this (consistently):

• logs
• code

This issue is not reproducible on my colleagues' computers and only my machine with Wayfire. Not reproducible under Sway.

Changing the code to this also causes the issue:

let window = libhelium::Window::new();
window.init_layer_shell();
window.set_layer(Layer::Overlay);

The problem seems to be that its buffers get attached before configure(). I've talked to the Wayfire devs (big thanks to everyone there!) and we've confirmed the issue comes from gtk4-layer-shell.

I'd be surprised if it has to do with the Rust bindings, since they are just an autogenerated wrapper of the C library, but we can leave this issue open so others can see it

I am able to reproduce this issue with the gtk4-layer-shell example "simple-example" with the following patch:

This appears to be an upstream issue, as the same reproducer works in the other bindings and in C as well.

Seems to be fixed by https://github.com/wmww/gtk4-layer-shell/pull/49 (thank you!)
