The side bearing is calculated incorrectly. It works fine in upright masters. Minimal test file attached.

Hi, was this fixed? The latest 3.5.1 (Sept 16) still has this bug.

I see it is fixed in G4 (as per the release notes), but I’m not touching G4 for now. Could this please be fixed in G3 as well?

This was fixed in Glyphs 4. Just ported it back to 3.
