Any X11 benchmarks out there?

Since the topic of general system benchmarks and MySQL benchmarks has come 
up again recently, I was wondering if anyone is aware of any X11 
benchmarks.  While X11 performance would certainly be greatly dependent on 
your video card, I could also see how it would stress IPC and the 
scheduler, as the benchmark application handed off commands to the X11 
server.  So, if there's a good benchmark, it would be useful in comparing 
5.3 to 4.11 to linux, etc.

The only X11 benchmark I could find in my quick searching is xbench, which 
is very old and doesn't appear to want to build (I didn't try to figure 
out why, I hate makefiles.)

Is anyone aware of something more modern?
