It's possible.  When a colour calibrated pixmap changes screens it is
very likely that the RGB values sent to the screen should change.  I
have not examined Xinerama in depth but if it abstracts the colour
management off the apps then it is more than possible that it will
break.  I'll have a look at the Xinerama spec.

If you are working with ICC profiles it would be sufficient if you send
image data in a colour calibrated space--something like sRGB, for
example.  As I said in a previous message, I am looking into these
problems as of now but I'm still trying to devise what is needed and
what infrastructure is currently available.  Maybe it is enough if you
can specify the colour space to XRender but I don't know yet.

Best regards,

David.
