Accent renders lighter on eacute vs oacute

1

Does anyone have any clue what could possibly be causing this? These are composite glyphs that use the exact same acutecomb component. At first glance, I would guess a hinting problem, but this font is not hinted.

Screenshot above is from Chrome on Monterey, but Firefox and Safari look the same, which makes me think the problem might lie inside the font file.

This is a larger project with wght+opsz axes, but the problem persists after stripping it down to one master and making a static export. I’ve subset it down to only the relevant glyphs, if anyone wants to take a look at the files:

The path direction in the “e” is wrong. That seems to influence the rendering of the composites.

Thank you! I didn’t know that the path direction could influence rendering like that. So I guess at smaller ppem sizes, the renderer adds or subtracts a small amount of weight to outer and inner paths, and the wrong direction on the ‘e’ path caused the weight adjustment to become inverted on the next component (the acutecomb).
