I am using version 3.0.6 on a Boox Max 3. Things have improved a lot. Thanks for your work, Mike.

There remain two strange problems and it would be interesting to know, if they only affect the Max 3.

1) My pen does have the eraser button at the back. If I use the pen to erase, the eraser-trace is drawn as bold line, but it starts with a straight line from the upper left position (coordinate 0,0) to the current position. It seems like there is missing an initial moveto(). This problem is not visible, when I explicitly choose the eraser tool.

2) If I select the highligher tool and draw with the pen, a normal thin black line is drawn instead of the bold marker line. It becomes the correct highlighted line if I change to another tool after drawing the line.

I have a Max 3 Lumi with the eraser button on the opposite end of the pen. The eraser works fine but only when the pen tool is selected. With any other tool it emulates the tool, so if I have the text tool selected it draws text rather than being an eraser, I don't know if this is by design although  I seem to remember using a different Onyx pen (with the button on the side) in my previous Max 3 like yours and I'm pretty sure that it could erase also when any other tool was selected not only the pen tool.
Also, I don't have the trace that you describe coming from the top-left corner

I can confirm problem No. 2 also in my Lumi but only when the highlighter freehand style is selected but it works correctly with the rectangle or line styles.
