That is asking for info not generally available.  However, I can toss in that 
mine is running on an old slow athlon xp1400, on a Mach Speed mobo with 
disabled built in video.  When the problem stuck up its hand and started 
waving at me, I solved it with the kind help of the guys on IRC that night.  I 
was running an older nvidia video card using the nvidia driver.  The card has 
since expired as nvidia stuff is wont to do, and an even older, 4 megs of 
memory nvidia card is in there now, running just as well.  Back to the story 
however:

Switching to the nv driver helped the latency quite a bit but it was too slow 
for good backtrace graphics in axis.  On a hunch I switched it to the vesa 
driver and that solved 98% of the remaining problems and it was fast enough 
for axis to draw a decent trace.

You might want to consider some experimentation along those lines.

I suspect the haunting will continue until the cause is found and evicted.
