Nodes move when adding small objects

[CreativeTim]

I am using the latest version of Affinity Designer (2.2.0) on my Windows 10 desktop PC.

When adding multiple very small objects together the combined shape is sometimes not the same as the combination of objects before adding. In other words, if I were to make a copy of the group of objects I want to combine, after adding the copied objects together, the new combined object does not overlay perfectly with the original group of objects:

     

Depicted above: objects before combining in grey (left) and new combined object in red (right). File: Add-Artifact Test.afdesign.

Upon adding the objects AD seems to create new average nodes between the objects resulting in a distortion of the shape (I can provide more images with explanations if that is necessary).

I tried to reproduce the artifact with different but similarly sized objects and was able to reproduce the artifact for some of the objects. I have not been able to figure out why it happens in some cases and not in others:

The smallest distance between two nodes in any of the objects that I am trying to add together is 0.004 pt.

I tried disabling hardware acceleration, but did not produce a different result.

It may be months or years until that bug gets fixed, so would you like a workaround?

Hi @CreativeTim,

I've replicated this issue using your sample file and have logged this with the developers. 🙂
