Thanks for sending that along. Both do appear to have the same number of frames so there’s nothing intrinsically different about the export.
I tested the document using the v3.5 engine and got an even larger size than the 1.6 MB version, yet all my tests with the v3.6 engine resulted in the 143 KB size.
I’d be curious to know about any setup/configuration differences between your two machines like:
- versions of Hype (and it looks like you already said macOS was 10.13.4 on both)
- mac model number and display hardware used
- display color profile
- display resolution (that is, retina vs non-retina)?
- any custom homebrew installations of libpng or imagemagick/convert?
