If you enable stylus mode with that device, and then try to draw with the stylus, does it work? If so, then the OS is correctly distinguishing between touch input and your stylus input. That doesn't work with a capacitive stylus - the tablet can't tell the difference between the stylus and a finger.
The preinstalled PDF annotation app on the Boox 2 is utilizing some kind of API for faster redrawing or refresh rate. I don't know if that's something that external applications can access. If you install any other kind of application that utilizes touch input (such as a simple drawing app), do you experience the same kind of delay? It would help to know, because if not, then there may be a different approaching to drawing that is faster. If so, then this is a general problem with that device that can't be overcome without accessing functionality specific to the Boox 2. I do see an Onyx SDK here https://github.com/onyx-intl/OnyxAndroidSample but I don't know if that works with the boox 2.
