Short description of error
I tried out the recently added "convert mesh to Grease Pencil", and I found out this issue, typically happens to long objects.
Exact steps for others to reproduce the error
Based on the default startup or download the attached .blend file if you want
- Scale the cube up along the X axis to make it long, so that it can be easier to observe
- Covert the cube to Grease Pencil
- Move the view closer and rotate around, at certan angle the strokes are going to disappear
P.S. In the attched .blend file I keyframed the camera so you can just hit the space bar to play and see it happens.
