[GRASS-dev] [GRASS GIS] #1618: d.rast.arrow displaying incorrectly in GRASS 7

#1618: d.rast.arrow displaying incorrectly in GRASS 7

--------------------------+-------------------------------------------------
d.rast.arrow gives a variety of incorrect displays in GRASS 7, with
multiple arrow for each cell and a change in arrow resolution when the
align to grid option is chosen. It also does not display when the
transparent option is checked for the null colors. The same problems occur
with the Cairo and PNG drivers.

It is working correctly in GRASS 6.4.3.

I've posted screenshots of the same display (wind direction and velocity
in AD 1000 in the N. Atlantic, in case you are wondering) from GRASS 6.4.3
and GRASS 7 to illustrate the problem

Comment(by cmbarton):

This is one of a series of rendering errors that have appeared in GRASS 7
(see also ticket #1410) that are making it hard to get nice output from
GRASS 7. There are also problems with north arrows and grids. If these are
related to the same underlying problem, all could be fixed at the same
time. Do these problems show up on non-Mac systems?

looks ok for me now in spearfish. do you still see it? maybe only in a
lat/lon location like the d.barscale bug?
