This is more or less the same as #274, which I believe was falsely closed. When that issue was filed, CompositeAlphaMode was not yet exposed in wgpu, which meant that pixels could not configure it to make transparent windows work. #274 was then closed when the upstream wgpu issue was resolved. However, pixels was never actually updated to use the now-exposed CompositeAlphaMode API, and it is still hardcoded to use the first one (which appears to be Opaque all the time):

pixels/src/builder.rs

Line 322 in d140eba

let alpha_mode = surface_capabilities.alpha_modes[0];

Therefore, the issue with transparency still persists.

I'll accept a PR to allow setting the alpha mode in the builder.

See also #274: wgpu still only supports opaque surfaces, at least on Windows 11/Nvidia.
