Running tour example crashes

Thanks for the report!

The panic is most likely caused by a lack of compatible graphics adapters. The unhelpful error message is a wgpu issue: gfx-rs/wgpu#368

Could you share more details about your environment? If you are on Linux, ensure you have Vulkan drivers installed (you may also need Vulkan utilities).

Than you!

I am using Arch Linux. I installed Vulkan following ArchWiki . Now the example runs successfully, but all the texts are displayed as squares.

After changing this line https://github.com/hecrj/iced/blob/b31a80f2c0ca198f1bf0206618654415d2da460e/wgpu/src/renderer.rs#L68 to some font title I found using fc-list and now text shows correctly.

.load(&[font::Family::Title("方正华隶简体".to_string()), font::Family::Serif])

Thank you!

This is a hard problem to solve. It is part of the roadmap (see #33).

The author of skribo did some interesting research that may be useful once we decide to tackle this: https://github.com/linebender/skribo/blob/master/docs/script_matching.md
