When I click twice in quick succession with my Wacom tablet (like when drawing dotted lines), Aseprite joins the second click with the first. Here’s a video of it happening: https://i.imgur.com/Oomi5IH.mp4
This does not happen with a mouse, and does not happen on other drawing programs. I tried adjusting the “Double-Tap” settings in “Pen and Touch” in the control panel to make the timing-window and distance as small as possible so it’s a little bit better, but it still happens sometimes.
I’m using a wacom Intuos on Windows 10, Aseprite 1.3-rc6
