Font Rendering issue in Adobe

I’m facing a problem in just a single letter and I do not know what it is called, sometimes happened and sometimes not:

I do not think it is a kink, here is the letter in glyphs:

I tested the letter in FontGoggles and there is no issues, I export it as a variable font. There are no autohint or manual hint.

Would you mind sending me a file for testing (in a private message)?

Hmm, odd. I can’t see anything wrong with your path directions (at least not in most glyphs, some glyphs do have wrong path direction set). However, quite a few glyphs show these artefacts, and they all occur on overlapping path segments (including open corners). Closing these open corners fixes the issue. The exported variable font has these open corners and overlapping paths still included. This is standard, however, so I don’t see why this is leading to rendering problems in Adobe app.

Good rule of thumb: if it works everwhere except for in Adobe apps, it’s an Adobe bug. Nothing much you can do about that.

I have seen issues like that. Sometimes it helps to move the first node somewhere else.

That is indeed something I wanted to add: The first node was always at a very untypical spot. Try using the automatic path direction correction, which will move the first node to the bottommost leftmost node.

Got it, thanks!
