Semi-transparent textures render incorrectly

[Nokola]

To reproduce:

1. Attempt to render attached texture hs.png
   

Expected:
texture renders with smooth and low opacity

Actual:
texture renders with high opacity and black border

Notes:

1. I have set game_config_mut().bloom_enabled = false; in setup()
2. Is this sRGB vs linear color handling issue?

Drawing code:

        draw_sprite_rot(
            info.ship.into(),
            vec2(trans.x, trans.y),
            WHITE,
            1,
            body.rotation().angle(),
            info.size / 2.5,
        );
