That didn’t work, unfortunately. I did find out though, that this happend only when it’s in a group and you scale the group. So I can workaround this, but I don’t understand the reason for this or if this is a bug.
Update 2022: Still working on it. This requires that we transition the Principle mac app off of core animation to our own rendering system, the one we use for share to web in the browser. Hoping to have it released this year.
