Platforms: OS X 10.11.5, Debian Sid Linux 4.6 SMP Kernel.
GNOME: 3.20.3.
MyPaint 1.2 and Krita 3.0 release.
On Linux and OS X the Freehand brush produces no visible output to display, but all other drawing primitives for Rectangles, Ellipses, etc., work. What does MyPaint rely on beyond evdev event calls to coordinate the tablet and pencil to screen?
Is there any debug option to see output to console and find out how is it that though the events are active on the tablet what gets drawn to screen is actually nothing as I move the pencil around the tablet when using the freehand brush.

NOTE: Debian is not current on GDK Pixbuf as it is a minor release behind:
https://www.0d.be/debian/debian-gnome-3.20-status.html
gdk-pixbuf installed is 2.34.0-1
Debian needs packaging for 2.35.1
I would be interested to know if this turns out to be the culprit.
The results still show no output from the freehand brush.
