Sometimes Lines Strokes do not draw on canvas.

[jimkricket]

I have a small Intuos4 small, model PTK-440 with the latest wacom drivers: Windows - Driver 6.3.22-6 (Win 7, 8 and 10*).

Windows 10, 64bit.

When I drawing on Paintstorm with my tablet pen, sometimes line strokes are not drawn on the canvas.

Note: I do use Clip Studio Paint, Medibang Paint, Black Ink and Krita as well, and drawing strokes works just fine.
