Parametric filters producing multicolor artifacts

[Zhyanno]

App version: 26.9 m.3133

macOS Sequoia 15.4.1 (intel mac)

Steps: any attempt to use parametric filters produces this result. The example photo is a single-layer .jpeg. It does not have any other filters, layers or effects applied prior to trying to use the parametric filters. I also tried .png and .psd images, the problem was still present. Larger image resolutions produce an even worse result.

Expected Result: Parametric filters looking as advertised

Actual result: all filters have what looks like some kind of extreme multicolor artifacting. The artifacts move when properties are changed (resolution included), but never go away. See attached screenshots, including shot showing image size and resolution.
