Bevy version

0.15.0

What you did

When ImageFilterMode::Nearest is set as the default sampler, tearing occurs to text, sprites, etc. when the window resolution is an odd number (101x303, etc.). You can test by spawning a sprite and then resizing the window:

use bevy::prelude::*;

fn main() -> AppExit {
    App::new()
        .add_plugins(DefaultPlugins.set(ImagePlugin::default_nearest()))
        .add_systems(Startup, setup)
        .run()
}

fn setup(mut commands: Commands, asset_server: Res<AssetServer>) {
    commands.spawn(Camera2d);

    commands.spawn(Sprite::from_image(asset_server.load("grid_480x270.png")));
}

The notable exception is that it doesn't happen to sprites with dimensions that is the power of two (512x256, etc.).

You can test a more elaborate, interactive reproduction here: https://github.com/musjj/nearest_filter_bug. Slowly and gradually resize the window and you should be able to see the artifacts popping in and out.

What went wrong

Visual tearing occurs.
