Hi all,
We have been using Batik for a while and it's been working beautifully.
The other day however we saw a strange new problem. It hasn't happened
again but I'm wondering if anyone else has seen this kind of thing before.
Basically we have a floor plan and we dynamically (via Java) fill in
the room areas with various colors, by setting the "fill" attribute
on the room's <polygon> to e.g. "url(#roomColor.Green)", where in the
<defs> section we've defined the various colors, e.g.:
<linearGradient id="roomColor.Green">
<stop offset="0%" stop-color="#33ff33"/>
</linearGradient>
What we saw the other day was these two anomalies on the screen:
1. A couple of rooms (call them X and Y) that were supposed to be grey
were 1/2 the right color (top half) but the bottom half was painted
with a "snapshot" of another room (call it Z). That is, in the bottom
half of X and Y you could see Z's room number along with it's green
coloring: a snapshot of Z rendered within the boundaries of X and Y.
It's as if the rendering engine forgot to reset it's buffer after
painting Z before painting X and Y, or something like that.
2. Next to, but outside of, room Z was a little rectangle of green
pixels that were completely out of place (nothing should have
been drawn there).
This happened on two different machines that happened to be displaying
the same map, so it doesn't seem to be a "random glitch".
I am pretty certain that we are performing all updates within the
update manager thread.
Thanks for any insights,
-Archie
P.S. Should I file a bug even though I don't have a test case (yet)?
