Is your issue REALLY a bug?

• My issue is indeed a bug!
• I am not crazy! I will not fill out this form just to ask a question or request a feature. Pinky promise.

Is there an existing issue for this?

• I have searched the existing issues.

Is this issue related to iced?

• My hardware is compatible and my graphics drivers are up-to-date.

What happened?

When I try this on,

$ git clone https://github.com/iced-rs/iced.git
$ cd iced/
$ cd examples/
$ rustup update stable
$ cargo run --package tour

The Environment is Window10 and Visual Code. The last one (cargo run --package tour) did make an error. Before that, all compiled well.

What is the expected behavior?

Version

crates.io release

Operating System

Windows

Do you have any log output?

I believe this is the same WGPU init bug that plagues many older drivers / integrated graphics. The issue is that WGPU initializes all of the devices in order to pick the most optimal (So you can run into issues like this). This should be forwarded to WGPU team.
