Weird yellow background when using Glur on macOS

[mpdifran]

Hey all!

Loving the Glur library, super cool stuff. I've recently integrated it into my App Store screenshot app, and I've noticed some weird behaviour on macOS in particular.

Glur functions as expected on iOS and iPadOS, but when I view the same Glur on macOS, I get a yellow background. Have you seen this before? Any idea what's going on?

Note: The app tint is yellow, so perhaps the yellow is coming from there?
