What went wrong

Text is 'glitching' on my Windows machine, as shown in the following screenshot:

This issue is NOT reproducible on my NixOS machine, but is reproducible on both of my Windows 11 machines (possibly of note: both are using AMD cards).
It's not an issue with my text files, I tested some basic ones. The pattern of glitching is the exact same each startup, regardless of window position or size. Changing the position or scale of the text will result in the pattern changing, so I suspect this is a rendering issue.

The text object is generated per The Book's example:

    commands.spawn((
        GUIScrollText {
            id: String::from("text_ui")
        },
        TextBundle::from_section(
            "Nayu_todo",
            TextStyle {
                font: asset_server.load("fonts/ALLER.ttf"),
                font_size: 100.0,
                color: Color::WHITE,
            },
        ).with_text_alignment(TextAlignment::Left)
            .with_style(Style {
                position_type: PositionType::Absolute,
                position: UiRect {
                    bottom: Val::Px(215.0),
                    left: Val::Px(335.0),
                    ..default()
                },
                ..default()
            })
    ));

It's brought in via a startup system with the following setup:

pub struct ChatController;
impl Plugin for ChatController {
    fn build(&self, app: &mut App){
        app.add_startup_system(import_gui_sprites)
            .add_startup_system(spawn_chatbox);
    }
}
fn import_gui_sprites( mut game_state: ResMut<VisualNovelState>, asset_server: Res<AssetServer> ){

And finally, the plugin is dropped into the main app:

fn main() {
    App::new()
        .add_plugins(DefaultPlugins.set(WindowPlugin {
            primary_window: Some(Window {
                title: String::from("Ettethread - Requiem"),
                resolution: (1280., 800.).into(),
                present_mode: PresentMode::AutoVsync,
                // Tells wasm to resize the window according to the available canvas
                fit_canvas_to_parent: true,
                // Tells wasm not to override default event handling, like F5, Ctrl+R etc.
                prevent_default_event_handling: false,
                ..default()
            }),
            ..default()
        })) 
        .init_resource::<VisualNovelState>()
        .add_startup_system(setup)
        .add_plugin(Compiler)
        .add_plugin(BackgroundController)
        .add_plugin(CharacterController)
        .add_plugin(ChatController)
        .run();
}

This looks similar to #7944

[hiibolt]

I agree, I'm running Vulkan. How do I use DX12 to verify that's the cause?

[ickshonpe]

Do you get the same corruption when you use Text2dBundle?

[hiibolt]

Issue not present with Text2dBundle!
Issue not present when using DX12 as backend!

Notable overlap between the issue and reproducible test cases:

• Common denominator of Vulkan backend
• Both of my machines and @AmionSky's machine are running Windows 11 Pro (22H2)
• Both of my machines and @AmionSky's machine use 6-series AMD cards with proprietary drivers

reopening as #9169 was reverted in #9237

I'm seeing the same issues, but with more than just UI. I also see it with sprites.
