On my Waterfox 6.5.6, it opened but remained blurry when zoomed in. MS Paint refused to open it. The GIMP v2.99.18 crashed and took my display driver with it. Windows 10 Photo Viewer surprisingly managed to open it and keep it sharp when zoomed in. The GIMP v3.0.2 (latest version at the time of writing) crashed.
