I did some more testing and it seems as though the monitor,
combination of identical monitor models or VGA port on the monitors
might be the issue.

The monitors I am using are identical AOC's.  Product Name:
e2250Swda, Model No:  215LM00019.  I had a older spare Benq monitor
E2200HD with native resolution of 1920x1080 and swapped it with the
VGA connected AOC.  Everything worked fine on both displays with
1920x1080 without disabling EXAPixmaps!
I then swapped it around so AOC on VGA and Benq on DVI and the
corruption came back.  I also swapped out the AOC's in case the issue
was with one of them but same problem on both.

Previously even if I disabled the VGA port with the AOC attached to
it, the AOC on the DVI port would still get display corruption.  With
the Benq connected to VGA but disabled no corruption occurs on (either
of) the DVI connected AOC.

I have attached an xrandr --verbose for both combinations in case it
shows something useful.  I couldn't see anything that might explain
why sorry.

Thanks again.

James
