Thanks for the input!
In our situation, we incorporate SVG as a fo:instream-foreign-object so I
can't remove the dependency. Does anyone have any advice on how we can
improve the configuration (for instance, different Xvfb parameters maybe?)
or is it solely a function of the OS/version, JVM/version and X/version?
Thanks...Jon
