I tried the patch but it made no difference, however I think I have found a
solution to my problem.
For some reason I decided to change the video lead from the RV516 card to the
monitor (an HP LP2065) the card supports both the old 15 pin analogue and the
newer digital socket types. Changing the cable from digital to analogue has
"fixed" the problem. I have many cables of both types and a second LP2065
monitor the problem always appears with a digital connection to the RV516. Do
you think this is a quirk of the particular RV516 card I have or something
associated with the driver ? If the latter and you think it worth investigating
further I am willing to do more work on this problem (I do have a RV710 based
card that I could swap in and test that combination of driver, cables etc. ) or
should I leave the problem as "fixed" and move on ?

thanks for your help anyway.
