I’m doing some more testing with variable fonts and just noticed that I’ve got a pair that, when used on Chrome 68, OSX 10.12, is overkerned (the glyphs are touching) when the kerning appears fine in Glyphs/Photoshop.
Here are some screenshots of the apps. Is this a known bug? I cleaned up/compressed the kerning no changes. This is exported from the latest Glyphs cutting edge (2.5.2 1165).
