Ok, well that's my exact system... hrm...

Yeah, that's the version bump in which I changed the font dpi, but  
that should not affect this behavior.  In fact, I seem to recall  
enumerating each change in the server between beta1 and beta2 and none  
of them seemed related...

Yeah, I think the ~/.xinitrc.d stuff got added around beta3 or rc1...


Sorry, unless I get some more info, there's not really much more I can  
do here.  There was one person reporting high CPU usage on Tiger, so  
hopefully that might pan out to something...

In fact... would you mind installing MacPorts and doing a 'sudo port - 
v install xorg-server'?  Then run /Applications/MacPorts/X11.app ...  
atleast then I might be able to feed you Portfiles to use to pull in  
older versions to start bisecting this.
