Transformation not being applied to anchors correctly

In Glyphs3, when I apply a skew transformation to a glyph, it moves the anchors incorrectly. If I undo the action and reapply, it’s even worse.

Here’s a test case.

I’m currently using a trial of 3.0.4 (3108)

How exactly do you apply the slanting? From the Transform panel? What have you set as the transform origin?

From the transform panel using with any origin.

I can’t reproduce this. Could you send me a screencast that I can see what you are doing?

I think this might be related to Anchors slant too much.
