Hello,
I have noticed some issue with of previewing overlapped components.
I made many glyphs out of components, because the font is very complex.
But I did not notice the problem until recently – in inDesign (exported font).
In glyphs it does not show the problem, when glyph is made out of components. I only see the problem, when I place contours from both components into one glyph.
Appears to be a grid rounding issue. You can either find a better spot on the grid for each of the nodes, or move the nodes that need to be aligned on top of each other.
Yes, I know how to fix the problem. Actually in Glyphs 3 it is visible where the problems are. At least when I put contours on each other into one glyph.
But I do not see any problem when the glyph is made out of components. It does not show any problem (grid rounding issue) in Glyphsapp, only in exported font.
