Bug / Limitation with intersected photo

[instinctive.de]

Hi,

can anyone imagine how I can successfully export this project?

In the attached file, there's

1. On the left, a photo that has been posterized by using a contone and a hard fill profile,
2. In the middle, a bunch of Janinas,
3. On the right The result of the intersection of the former two.

However, as soon as I zoom further into the view, the intersected result gets completely distorted and unusable - this happens even on export.

Seems to be a bug - has anyone ever seen this happen?

Thanks
