Your mouse only delivers pixel coordinates. So if you stroke a paint,
GIMP gets delivered a handful of pixel coordinates and interpolates a
paint stroke between them. If two subsequent coordinates have the same
horizontal or vertical coordinate, you end up with a line that is
aligned with the pixel grid.

If you are using a tablet, the tablet should deliver higher precision
coordinates. But is that actually the case? Are you really using your
tablet as extended input device or is it only delivering core pointer
events for some reason?
