I found that if I reduced the screen resolution to 800 x 600 it improved the situation such that it was only flickering with another scene/room. I was however able to then keep playing through.
Once I got to the big hangar in bast castle the problem seemed to resolve itself and I was able to put the resolution back up to the next level.
It suggests to me that there is something odd about JK3 data file pertaining to this particular part of the mission.
