What you say 'canvas' do you mean the Batik JSVGCanvas? Or your
personsal SWT Canvas?

It is essential that you not modify the document while a paint is
in
progress. If the renderer detects this condition it will generaly abort
since it's impossible to get a reasonable result.
The only other thing I can think of would be if the clip (or other
attributes) of the Graphics2D was weird.
