On my Max Lumi I found something which is not working correctly. If I change to annotation mode and choose the crescendo (or decrescendo) tool to draw a crescendo, only the stroke path (as with the pen tool) is drawn on the Eink screen. It only seems to be a visual thing with the boox drawing library, because in fact, the crescendo sign is created and shows up when the annotation mode is closed.

I wanted to create a video showing this behavior, but on the video everything is drawn correctly. So it really seems to be a thing with how boox handles pen strokes. @Mike: Maybe you can have a look at this with your boox devices?
