Does radeonhd use XAA? If so, and your X server isn't up-to-date (this 
has recently been made the default), add the following to the Device 
section of xorg.conf: Option "XAANoOffscreenPixmaps" "true".

 	I've been using modular-x11 from pkgsrc (and have the latest
 	as of yesterday). I'll test out with that Option - thanks!

 	Out of curiosity, do people tend to run X from xsrc or
 	pkgsrc nowdays?

Ah, I only made that change to xsrc, so you will need the option still.

Cheers,

 	Adding 'Option "XAANoOffscreenPixmaps" "true"' does make
 	the problem go away formodular xorg from pkgsrc - thanks!

 	Is the general consensus to prefer xsrc to modular xorg
 	from pkgsrc now that xorg has been imported? Does anyone
 	know how closely xsrc will track xorg, and will it be
 	possible to build a current xsrc with a netbsd-5 tree?
