0.1pt line width shows as two thicknesses

[DrRose]

Hi,

I've used Affinity for some time but for only for illustrative purposes and never for very technical/precise work, so please forgive me if this is very obvious.

I need to set up a file for laser cutting using a  0.1pt stroke width for the cut areas. My issue is that 0.1 pt is showing up as different thicknesses throughout my files. If I click on the circles in the screenshots, both circles are showing up as 0.1pt, but to the naked eye it is clear that one is thicker than the other. If I slide the width up or down it will show 0.1 pt, 0.1 pt, 0.2 pt, 0.2 pt, etc., so I'm wondering if maybe one width is 0.15pt or something similar but is not showing that way?

Any help figuring out which thickness is "correct" and whether I have done something weird here would be much appreciated!

Thank you! This must have been the issue, the smaller one was indeed 0.5 pt
