Round-trip Dump and Build appears to change GPOS kerning

[MalcolmWooden]

Original font has no kern here.

After Dump and Build a new kerning pair has appeared.

Json difference?

Also OTFCC does not support legacy kern table. Only GPOS would be processed.

Looks like a bug when generating individual-based lookup from class-based...

@MalcolmWooden Could you please provide me the file so I can test?

I tried one roundtrip (using Master version) and does not have any problem. I know there are some older version that breaks kerning lookups. Maybe you can try to build with Master.

Sorry but I am not familar with building projects with Premake and Lua. Do you have a Master Mac O/S version you can upload?
