Did you at least test this locally? I'm hesitant to include support if it's been completely untested.

Sure, i test it with wgpu-template and change to the following code:

// graphics.rs
pub async fn create_graphics() {
    // old
    // let instance = Instance::default();
    
    let wids = wgpu::InstanceDescriptor {   
        backends: wgpu::Backends::GL, 
        flags: Default::default(),
        backend_options: Default::default()
    };
    let instance = Instance::new(&wids);

You can see the source code with wgpu-demo-with-winit

And vulkan mode need to update the latest ash version see detail ash-rs/ash#983

how hard would it be to add a (build-only) ci test for this target? If that's just another rust toolchain to include that should be definitely done, otherwise it's just a question of time when this breaks again

Even if it's tier3, we already have a tier3 path in CI, so shouldn't be that bad

Right, i will add it. But when i use this patch to test examples with wgpu-in-app, shadow and water crashed. I think i need to fix them before merging this PR.

Don't feel pressured to fix those first. We can land support one step at a time.

I've already add it, but i'm not certain if it aligns with your expectations.Hope your fallback and i'll fix it try my best :). @Wumpf
