Thanks for sharing the issue. This is related to a recent change in Processing 4.4.3. We updated the default `pixelDensity()` setting to match your display’s density, which makes sketches look sharper on high-DPI screens, but it can also affect how images are drawn.

To fix the issue in this example, try adding `pixelDensity(1);` inside the `setup()` function. That should make the image fill the window as expected.

Let us know if that works!

Current workaround pixelDensity(1) in the setup() function to force Processing to render at low-dpi scaling.
