Bug Description

I use the calligraphy tool quite often with my Wacom pen tablet and
encounter the problem described here frequently:

igraphy

"A stroke made using a Wacom tablet with pressure sensitivity may create a
mess at the beginning of the stroke or where there is a quick change in
direction. This is especially true when the Fixation is set to a small
number."

Of course it's possible to clean the stroke up, but Inkscape shouldn't
create such a mess in the first place.

this does not only happen at the beginning.
it happens every time the drawing speed gets very slow.
(at the beginning and the end of strokes, and on sharp corners, 90 degrees or more)
the most extreme case is just holding the pen down:
every jitter is taken as a drawing action in a basically random direction, creating the mess.
(this effect may be restricted to certain driver/os versions, i'm on windows)

this is especially annoying since it triggers bug 184550.

it would be nice if the tool would sanity check the input to distinguish between noise and real input. maybe a tolerance value (like in the freehand tool) would do.

Perhaps making the draw point lag behind the input by a small distance, say 1/32 pixel. You could call it a feature and let it be user settable. HTH
