Android e-ink optimization

unfortunately, drawing with joplin on an android e-ink tablet is not so great.
it's good that there's finally a function for inserting drawings.

unfortunately, the drawn lines are displayed with a delay, which is nerfy when drawing.
unfortunately, the standard app and oneNote still work much better, as you can see the drawn line directly.
so it is feasible that it is displayed much faster on e-ink displays.

or are there already optimizations that I haven't found?

I'm linking a related discussion thread from a user for drawing with Joplin on a BOOX e-ink tablet:
