iced: Panic when running any of the examples under Linux Intel GPU

Running cargo run --example tour causes panic with the following stack trace (snipped):

I’m getting this also on linux. The error message tells nothing, but the extended stack says its wgpu :

  15: core::option::Option<T>::unwrap

Edit: okay the fix for arch linux is to install vulkan-intel

I have opened #74, which should fix the issue.

Sorry to hear that.

This is one of the main reasons I think having a renderer alternative is important. iced_wgpu still needs to mature quite a bit.

In the meantime, maybe we could avoid panicking in wgpu_glyph and embed a fallback font that is guaranteed to work for these cases.

I also have this issues, as all my fonts are OpenType fonts, specifically NimbusSans for sans-serif, NimbusRoman for serif, and NimbusMonoPS for monospace.

I believe these fonts are from KDE which is my desktop environment on Arch Linux.
