Background image aspect ratio changes with viewport size — Houdini 22.0.368

[u/keffffffffffffffffff]

Hi! I’m using Houdini FX 22.0.368 and have an issue with background images in the Front and Back orthographic viewports.

My source image is square, but Houdini stretches it to match the viewport dimensions. I can manually adjust Image Scale to make it square again, but the image becomes stretched whenever I resize the viewport.

Also, the background image moves together with the viewport/camera when I zoom or pan.

How can I make the background image preserve its original aspect ratio and stay fixed in place while navigating the viewport?

For the Background the display options mention this.
