Window transparency broken on Windows #7544

Open aevyrie opened 1 year ago

Bevy version

main

The transparent_window example appears to have broken.

Can't seem to repro this myself, going to try updating my drivers. Maybe should try a cargo clean/cargo run --example transparent_window

Same issue occurred on Mac OS on Metal. SystemInfo { os: "MacOS 12.1 ", kernel: "21.2.0", cpu: "Apple M1", core_count: "8", memory: "8.0 GiB" }

mockersf commented 1 year ago

This is known, see the docs on https://dev-docs.bevyengine.org/bevy/prelude/struct.Window.html#structfield.transparent

I opened a PR to improve the situation on macOS: https://github.com/bevyengine/bevy/pull/7617

On windows, it should be fixed by latest winit update, but I can't confirm it myself.

james7132 commented 1 year ago

Can confirm that the latest winit update has fixed this on Windows.

mockersf commented 1 year ago

Doc should be updated to remove mention of issues on windows: https://github.com/bevyengine/bevy/blob/2344b943a2f65031200a19d314b328a2eea320ae/crates/bevy_window/src/window.rs#L130-L135

aevyrie commented 1 year ago

This appears to be broken on main again. I've tried a cargo clean and running in release with no luck.

transparent_window example not working for me either. image

Aceeri commented 1 year ago

@aevyrie @morfert Could you try running the winit example here? https://github.com/rust-windowing/winit/blob/master/examples/transparent.rs

Will see if I can repro again this week.

morfert commented 1 year ago

I cloned winit and ran cargo run --example transprent but the window was not transparent. image This may be a winit problem.

Aceeri commented 1 year ago

Investigating a bit and it seems like that might just be an issue with their example not drawing anything?

https://github.com/rust-windowing/winit/issues/2502

SecretPocketCat commented 1 year ago

This might be a red herring, but blur and similar decorators were broken in the tauri-adjacent crate on Win 11 22H2 https://github.com/tauri-apps/window-vibrancy/issues/45

SecretPocketCat commented 1 year ago

This might be a red herring, but blur and similar decorators were broken in the tauri-adjacent crate on Win 11 22H2 tauri-apps/window-vibrancy#45

My bad, the bevy example is actually fine on Win 11 22H2.

morfert commented 1 year ago

Yeah, winit is probably fine I tried drawing something.

Transparent

With:

        WindowBuilder::new()
            .with_decorations(false)
            .with_transparent(true)
            .with_inner_size(size)
            .with_min_inner_size(size)
            .build(&event_loop)
            .unwrap()

Result: image

Not transparent

With:

        WindowBuilder::new()
            .with_title("Hello Pixels")
            .with_inner_size(size)
            .with_min_inner_size(size)
            .build(&event_loop)
            .unwrap()

Result: image

Conclusion

As long as something is drawn, winit seems to properly become transparent.

Addendum

The Not transparent test is the unmodified minimal winit example from pixels.

stefnotch commented 1 year ago

@morfert

Pixels might not be the best library to test this, because of https://github.com/parasyte/pixels/issues/370 That leads to it being either "fully transparent" or "fully opaque".

transparent-pixels-winit.zip

morfert commented 1 year ago

Using the following code:

    let window = WindowBuilder::new()
        .with_title("A simple window")
        .with_transparent(true)
        .build(&event_loop)
        .expect("Builing window failed");

    let instance = wgpu::Instance::default();

    let surface = unsafe { instance.create_surface(&window) }.expect("Could not create surface");

    for ad in instance.enumerate_adapters(wgpu::Backends::all()) {
        info!(
            "Adapter : {:?}\n Supported Alpha : {:?}",
            ad.get_info(),
            surface.get_capabilities(&ad).alpha_modes
        );
    }

I enumerate to see all supported alpha_modes for all adapters on my laptop. The results are as follows:

Only Opaque and Inherit are available. This might be the problem.

CoryRobertson commented 1 year ago

I also have transparency not working as well, are there any active workarounds?

edraze commented 8 months ago

Hi, are there any updates on this problem? Looks like transparency still not working(#10929), even with winit latest versions.

bradmesserle commented 7 months ago

How do we find gpu's that support PostMultiplied Apha Mode?

lunarcleint commented 6 months ago

Has they're been any update on this? transparency is still not working and now I'm noticing the examples just missing from the winit repo

bradmesserle commented 6 months ago

I also have this problem with AMD Radeon 680M on Win 11, only getting Opaque in the list of supported alpha modes. Not sure if that is related or not, but the transparency example on master does not work.

lunarcleint commented 5 months ago

This has been fixed on the latest bevy 0.14 testing, try it out :D

Off topic but why is there not a most current version number on the bevy website? I had to look in github. The getting started or the front page should have the most current version displayed.

IMHO.. :)

I had the same problem. I have to update NVIDIA graphic card version to get it working.

561.09 for NVIDIA GeForce GTX 1080 - the newest available driver - still doesn't work. The background is still black 😞

alice-i-cecile commented 1 week ago

This largely appears to be a winit bug: https://github.com/rust-windowing/winit/issues/2502. That said, the comments suggest a workaround that's worth investigating. It's a bit hacky to try and fix this at the Bevy level but maybe it's worth it?
