Okay Patrick, I have run a number of tests, and at all resolutions and 
colour modes available to me via the "control panel" display the demo 
distort displays the the same problem.

Also I did have -class TrueColor -depth 24 added to my 
/var/X11/xdm/Xservers for these tests though I reverted back to the 
original one.

another thing I noticed with distort, this effect depends on image size 
for example:
with an image size of 57k its fine
with an image size of 226k its fine
with an image size of 900k its not and displays the split image issue.

one you lock the target
two you bait the line
three you slowly spread the net
and four you catch the man
