This is with X server 1.20.0 and xf86-video-ati 18.0.1, so I concur.

I'll upgrade once I'm back near the machine in question (I mean, I could
upgrade now but I'm 200 miles away so running an X server on it at
present is a bit pointless).

It can clearly be caused by *something*, and without anything obvious
going wrong in the user interface you can clearly get crazy log flooding
without the user being any the wiser. It doesn't really matter what
causes it, just that it is causable. :)

Yeah, I stuck it in the wrong place in the mail. (I meant to move it and
then completely forgot. Mea culpa.)
