Exported TTF instances have the correct baseline in the browser, and the exported variable font WOFF seems to have identical vertical metrics to the exported TTF instances.
So I tried it on another one of my variable fonts and got the same result. Here is an instance of one of my fonts overlaid on the variable font using Wakamai Fondue. The variable font is the one that’s high on life:
Just to be clear here, this is something that started happening after updating to a newer version of Glyphs. If I wasn’t on the cutting edge, I assume it wouldn’t be happening.
I had a look at the file again. You send me three files. Two variable fonts that have the same creation date. Those two have some small differences that shouldn’t cause any difference.
Can you send me html sample files that show the “Old variable” and “New version - Variable”?
