I wonder if anyone can explain the unwanted diagonal lines which appear almost every time I touch the pen to my Huion H610PRO.
It doesn’t happen if I use the mouse to draw.
It doesn’t happen if I use MyPaint version 1.0.0
But MyPaint 1.2.0 is unusable (for me).
I’ve tried uninstalling and reinstalling.
Tried with Windows 7 on one laptop.
Tried with Windows 10 on a newer one.
Tried with the USB-connected pen, and a wireless pen.
Those lines keep appearing.
When I first started working with MyPaint, the lines didn’t appear. It’s a recent phenomenon. The pens work fine with all other art programs I’ve tried (Gimp, Paint, Photoshop, DrawPad, etc.) Can anyone suggest why this happens?
