Describe the bug

https://github.com/user-attachments/assets/bdb24ced-e0ea-4afa-9ec5-59061014604d

Changing the package name in Cargo.toml to overlay causes the window to have a black background.

To Reproduce
Steps to reproduce the behavior:

1. Copy the code from below or create a transparent window using Eframe and Egui

// src/main.rs

#![cfg_attr(not(debug_assertions), windows_subsystem = "windows")] // hide console window on Windows in release

use eframe::egui;

fn main() -> eframe::Result {
    env_logger::init(); // Log to stderr (if you run with `RUST_LOG=debug`).

    let options = eframe::NativeOptions {
        viewport: egui::ViewportBuilder::default()
            .with_decorations(true) // Hide the OS-specific "chrome" around the window
            .with_transparent(true)
            .with_position(egui::pos2(100., 200.))
            .with_inner_size(egui::vec2(300., 400.))
            .with_always_on_top(),
        ..Default::default()
    };
    eframe::run_native(
        "My egui App",
        options,
        Box::new(|cc| {
            // This gives us image support:

            Ok(Box::<MyApp>::default())
        }),
    )
}

struct MyApp {
    name: String,
}

impl Default for MyApp {
    fn default() -> Self {
        Self {
            name: String::new(),
        }
    }
}

impl eframe::App for MyApp {
    fn clear_color(&self, _visuals: &egui::Visuals) -> [f32; 4] {
        egui::Rgba::TRANSPARENT.to_array() // Make sure we don't paint anything behind the rounded corners
    }

    fn update(&mut self, ctx: &egui::Context, _frame: &mut eframe::Frame) {
        let panel_frame = egui::Frame {
            fill: egui::Color32::from_rgba_premultiplied(10, 10, 0, 5),
            ..Default::default()
        };

        egui::CentralPanel::default()
            .frame(panel_frame)
            .show(ctx, |ui| ui.button("Click me"));
    }
}

# Cargo.toml
[package]
edition = "2021"
name = "test-project"
version = "0.1.0"

[dependencies]
eframe = "0.30.0"
env_logger = "0.11.6"

[patch.crates-io]
egui = {git = "https://github.com/emilk/egui", branch = "master"}
# if you're using eframe:
eframe = {git = "https://github.com/emilk/egui", branch = "master"}

3. Run the code to make sure that the window is transparent
4. Change Cargo.toml to this

# Cargo.toml
[package]
edition = "2021"
name = "overlay"
version = "0.1.0"

[dependencies]
eframe = "0.30.0"
env_logger = "0.11.6"

[patch.crates-io]
egui = {git = "https://github.com/emilk/egui", branch = "master"}
# if you're using eframe:
eframe = {git = "https://github.com/emilk/egui", branch = "master"}

5. Run the project the window is now black

Expected behavior

The created window is (semi) transparent no matter the name of my package.
