Software render seleciton

[Wem-o]

I'm on the latest crates.io release of both iced-layershell(0.14.2) and iced (0.14.0).
I'm trying to use software rendering, with tiny-skia, as hardware acceleration would not benefit my app in any ways, and it just uses more memory. I disabled wgpu for both iced and iced-layershell like so:

[dependencies]
iced = {version = "0.14.0", default-features = false, features = ["debug", "fira-sans", "linux-theme-detection", "tiny-skia", "smol"]}
iced_layershell = { version = "0.14.2", default-features = false, features = ["debug", "fira-sans", "linux-theme-detection", "tiny-skia"]} 

Despite this, running cargo tree revealed that iced-renderer still has wgpu as it's dependency. I tried with a plane iced project, where i disabled the wgpu module, and it did not depend on wgpu. Since I don't have any other crate I suspect that iced-layershell is the reason wgpu gets included despite not being listed as an enabled feature.

I found a solution and set ICED_BACKEND env var to "tiny-skia" (ICED_BACKEND=tiny-skia cargo run), and from the memory usage it seems like it does use tiny-skia. (if ICED_BACKEND is set to software, it will panic tho, stating you need tiny-skia as a dependency, even tho you clearly have it).

I don't know if this is a serious enough bug, but I still wanted to share it for other who also want to use software rendering, but it'd be still nice to fix up the modules and make sure of wgpu isn't listed, it doesn't get compiled.

maybe because I export the features, but forgot to control it in this part..

I do not know.. Maybe there still something that I do not know about the cargo config

I think I have solved it now. I remove the dependence of iced for iced_layershell

Can you try rc1 to check if is solve your problem? thanks

I tried it, and now it won't even compile.
cargo deps look like this:

[dependencies]
chrono = "0.4.43"
iced = {version = "0.14.0", default-features = false, features = ["debug", "fira-sans", "linux-theme-detection", "tiny-skia", "smol"]}
iced_layershell = { version = "=0.15.0-rc1", default-features = false, features = ["debug", "linux-theme-detection"]}

With this I get:

 Compiling winit v0.30.12
error: The platform you're compiling for is not supported by winit
  --> /home/kinx/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/winit-0.30.12/src/platform_impl/mod.rs:78:1
   |
78 | compile_error!("The platform you're compiling for is not supported by winit");
   | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

To sanity check, I tried with the stable version, and with that it compiles without error.

iced = { version = "0.14", default-features = false, features = [
  "linux-theme-detection",
  "tiny-skia",
  "wayland",
] }
iced_runtime.workspace = true
iced_layershell = { workspace = true, features = ["debug"] }

it works but, on my platform

Ok... seems iced has a hard rely on winit.

I do not know..

maybe you should open an issue on iced
