Variable Font with Round Corners component issue

Glyphs
1

Hi all,
i’m trying to desigin a variable font with rounded corner.
I create a corner component for each master as shown in the picture, then applied to the 90° corners with center alignment.

This seems not to work with acute or obtuse angles like “A” or “V”. i tried to adjust the parameters and alignment but i still got spikes or angles at smaller weights/widths. (somtimes even for the 90° corners.

As a last resort i also tried to apply manually round corner to each glyph in each master but i still have some strange output when moving axsis at small weight.

Any Suggestion?

Can you show how you use the corner?
