Well, I was trying to find out if I needed to debug something for the  
greater good or work on a setup issue.  When your only response is to  
say it is expected and is a function of my hardware's lack of  
resources, that implies (at least to me) that things are behaving  
correctly.

Paul's response was quite helpful as it reminded me of what really is  
the core problem: negative coordinates in the theme and the opengl  
painter don't play nice.  Which is a bug.
