Transparent windows aren't supported in WGPU due to the misconfiguration of CompositeAlphaMode.

Is there an existing issue for this?

• I have searched the existing issues.

Is this issue related to iced?

• My hardware is compatible and my graphics drivers are up-to-date.

What happened?

You can't have transparent windows when WGPU is the renderer. Iced must pick CompositeAlphaMode:: PreMultiplied or PostMultiplied in order to support transparency, auto doesn't work like you'd expect.

What is the expected behavior?

Transparent windows work.
