Since the drawing code is identical for both machines, I feel confident in stating that this is a bug in the X server that was supplied with rs_aix31. ATK has proven to be a good test suite for X servers, in that we seem to use parts of X that no-one else has. As a result, many server bugs show up in ATK and are often mis-attributed to ATK. Unfortunately, there is not a whole lot we can do about them, outside of reporting them to those responsible for the X-server in question. Sometimes we can come up with work arounds, but trying to compensate for the failings of every X server in the world would be fighting a losing battle. Tom N.
