        }
    ],
    "unit": "px",
    "dpi": 300
}

2. Set minimal store scale: store.setScale(0.05)

3. Export store into image.

You will see that such text is blurred:

Why is it blurred? I think a stroke + shadow fire "buffer canvas" render logic. But because the scale is small, it produced smaller number of pixels. Do we need to fix it from the Konva side?
