Simple Copy/Paste into another document changes stroke width

[sbe]

The problem lies in the target document. But why? 

→ When I create a new document from scratch, copy/paste works.

The shapes are extracted from a more extensive layout, that's why there are so many clipping paths and groups. I didn't want to change anything for demonstrative purposes. If you ungroup all the groups, for example, it works. Still, a simple copy-paste should never change the look.

I have had the problem more often, so I would like to understand what the reason is. Thank you!

Different DPI for the two documents leaps out at me. But I would expect the copy paste to honour the point size of the strokes regardless.

Some time ago I also noticed that for some odd reason, Affinity treats points as bound to pixels, rather than to metrics or inches. And I didn't like it at all.

Yes, so true! And how Affinity converts internally should not matter, the important thing is that the proportions to each other must always remain the same.

I think there should also be the option in the main settings to always turn on "Scale stroke weight + Layer Effects settings with Object" by default (currently this is always off by default...)

So one day, Serif willing, all of these handy little settings should be possible in an advanced "Transform Studio-Panel" incl. proportional scaling

There's a known issue with copying groups -I've added this report to it

@Pauls Great! That would be amazing if the developers would have a look at this topic 😃

I also found this post while searching on the topic:

thank you, will try this, because I have the same issue with a logo I made in Affinity Designer

This is true, with same DPI no width change.

Pauls, this comment was over two years ago, and the bug is still there in V2.1. Bump?
