Hi.

http://www.w3.org/Graphics/SVG/Test/20061213/svg/animate-elem-04-t.svg
tests motion animation, where the blue triangle moves from the left pink
box to the one on the right.  I notice under Linux that as the triangle
moves over the right pink box, there is some strange rendering just at
the top of the triangle.  It’s as if the image it is compositing with
underneath (the pink box) is being sampled at one pixel below where it
should be.  Here’s a screenshot just before the animation finishes:

This occurs under Linux JREs 1.4, 1.5 and 1.6, but not under Linux 1.3.
If I set shape-rendering to anything other than auto, the problem
disappears.

I tried under Apple’s OS X JRE 1.5 and the rendering artiface doesn’t
appear.  I haven’t tested it under Windows.

What might the problem be?

Thanks,

Cameron
