Stroked Shapes Preview

Hello everyone,
For some reason, the display at the bottom of the screen shows Stoke-based shapes as a line rather than a full shape. Did I miss something or is it a bug?

Catalina 10.15.7
Using the latest Glyphs

3.0.3 (3079)

I’m facing the same problem since I updated the latest Glyphs app (3.0.3)
MacOS Big Sur 11.2.3.
It seems that only the preview is wrong since the file exports well.
(The thin lines are strokes, the arrow head is not)

Also, If you press “Show Pixel Preview” it works out temporarily.

Fixed it. For now, switch to the “-” in the instance selector. that should show the stoke properly.
