Desktop Window Tranparency Not Rendering Correctly

**Problem**

Dioxus fails to rerender properly when transparency is enabled in desktop mode, leaving the old material underneath the new frame.

**Steps To Reproduce**

```rust
use dioxus::prelude::*;

const STYLES: &'static str = r#"
#body {
display: flex;
}
p {
font-size: 100px;
}
"#;

const IPSUM: &'static str = r#"

sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

"#;

const BACON: &'static str = r#"

"#;

fn gui() -> Element {
let mut scene = use_signal(|| false);

let content = if scene.with(|b| *b) { IPSUM } else { BACON };

rsx! {
style { "{STYLES}" }
div {
id: "body",
onclick: move |_| {
let value = scene.with(|b| *b);
scene.set(!value);
},
p { "{content}" }
}
}
}

fn main() {
let window = dioxus_desktop::WindowBuilder::default()
.with_decorations(false)
.with_transparent(true);
let config = dioxus_desktop::Config::default().with_window(window);

LaunchBuilder::desktop().with_cfg(config).launch(gui);
}
```

I'm interested in fixing this myself but don't know where to start.
