--- Comment #11 from Sasha Kammakitz-jen sashakitz-jen@protonmail.com --- Hello, I'd like to explain a recent observation about pen pressure when trying out both Medibang & FireAlpaca through WINE on Linux Mint. I do believe pen pressure is being read in some way.
When doing a pen stroke with my stylus and graphics tablet, the very end of the stroke has anti-aliasing, while doing a stroke with the mouse or deliberately halting motion with the stylus before taking it off the tablet does not have this anti-aliasing.
I see no explanation for this other than the lowering pen pressure at the end of the stroke is being read. What is weird is that it is only at the end. Flicking into the stroke does not make it fade into the start, nor still does changing pen pressure affect the size and opacity of the stroke throughout. Only at the very end of a flicking-motion-stroke does this happen when using the stylus.
I hope this may lead to solving the issue so that pen pressure can work the way it is suppose to with these windows art programmes through WINE.
