Overlapping shapes not displayed in Edit mode

Hello!

I’m experiencing some strange behavior on all the glyphs and masters from a file, as if the shaped weren’t supposed to overlap (left). However, as you can see at the bottom, the shapes are rendered properly, and when I want to overlap the shapes it works.

I tried to copy and paste a letter to a brand new file, and the issue disappeared (right). I tried to correct paths direction but nothing changed.

May the file be corrupted ? If that were to be the case, should I copy and paste all my letters and masters into a new file, and is there a fast way to do that ?

(I tried to export an .ufo for each master then reopen them in glyphs, that works but I’m losing some layers)

The view on the left is what is shown when choosing the “Variable” font type in FileFont InfoOther.

To get the standard view, change the font type back to “Default” and run the following code in the Macro Panel:

Font.previewRemoveOverlap = True

Then, close the document and open it again.

Great! Thanks a lot!
