Got some mysterious background stripes when render a PDF page to Iced GUI

[videni]

hi, I am using Vello to render pdf pages inside an Iced GUI application, I found that Vello doesn't implement wgpu::TextureFormat::Bgra8UnormSrgb format yet, but Iced uses this one, I set the view_formats to wgpu::TextureFormat::Rgba8UnormSrgb and the format parameter to wgpu::TextureFormat::Rgba8Unorm,

 let texture = device.create_texture(&wgpu::TextureDescriptor {
            label: None,
            size: wgpu::Extent3d {
                width,
                height,
                depth_or_array_layers: 1,
            },
            mip_level_count: 1,
            sample_count: 1,
            dimension: wgpu::TextureDimension::D2,
            usage: wgpu::TextureUsages::STORAGE_BINDING | wgpu::TextureUsages::TEXTURE_BINDING,
            format: wgpu::TextureFormat::Rgba8Unorm,
            view_formats: &[wgpu::TextureFormat::Rgba8UnormSrgb],
        });
        let view = texture.create_view(&wgpu::TextureViewDescriptor::default());

it can render pdf pages to iced gui successfully, but got some mysterious stripes, any compatibility issues here please? If not, can I know how to debug this kinds of issues? I check my render pipeline tons of times, I am sure I didn't draw these stripes.

This issue is entirely unactionable, as it is not possible to reproduce this from the given information. Does this issue still reproduce on the latest main - I believe that we have landed a few watertightness issues.

If you are seeing that certain code creates artifacts in a texture drawn by Vello, please provide code to reproduce that scene, using only Vello rendering. Thank you!
