07/04/2023, 2:45 PMI'm struggling with implementing a drawing feature in a compose desktop project. The drawing process needs to be smooth and the user mostly is going to draw using a tablet with a Wacom interactive pen display so the experience needs to be good, something like Microsoft OneNote or any drawing app. On Mac and with a high display it works fine but on windows I start encountering some problems, specially when I try to draw something small. It looks like the drag positions are not precise. Any Ideas
