That's good news!

Sure, there's a delay, but it's not a problem.

This could be what I'm seeing! Is this setting configurable at all or can I 
simply find it in the code and change it before compiling? Maybe I need more 
RAM so the system can buffer the pixmaps.. I have 512Mb now. I don't get much 
swapping, but buffers get eaten into regularly.
