Ok so my computer is 64 bit windows 10 and I'm using an xp-pen star 03 tablet and I draw a line but when I pick up my pen to make a new line the little green cursor circle doesn't move even though I have my pen close enough to the tablet (I know because the mouse is moving but not the circle) and when I draw a new line the two separate lines get connected by a somewhat transparent line that is perfectly straight connecting the end point of the first line to the beginning of the second. I'm not really sure how to fix this, does anyone else know?

Sounds like https://bugs.kde.org/show_bug.cgi?id=363284 -- which we haven't been able to fix because our yiynova doesn't show that problem, and we don't have ugee or xp-star hardware to test with. It's also been reported that it only happens with some driver versions.
