Yeah it a known issue we are having with our WIndows builds. It also could be an issue with the graphics tablet especially if it’s not a Wacom device. The problem lies in the framework(GTK/GDK) we use to display the program so technically I believe it’s an upstream issue for us. It is being worked on, but it will take some time. I would encourage your subscriber to come over here so we can get the information we need from that person.
