Changing the following line:

https://github.com/lapce/floem/blob/17ffb5577d9519d04b1871b01e60da70f0765b11/vger/src/lib.rs#L31

To:

let instance = wgpu::Instance::new(wgpu::InstanceDescriptor {
    backends: wgpu::Backends::PRIMARY,
    dx12_shader_compiler: Default::default(),
});

Fixes the issue. The issue only happens when using the GL backend.

I'm using Ubuntu 22.04 running in WSL2, on top of Windows 10 build 19045.

Research direction

Reproduce the failure with cargo run -p counter under WSL, then start at src/renderer.rs:18 and follow the device setup into vger/src/lib.rs:43. Use the backtrace and examples/counter/src/main.rs:88 to trace the startup path; done means the examples run under WSL without the device-request panic.
