The flickering there doesn't need the > same buffer open in two different frame types. Do all the 3 buffers change simultaneously, due to some Gnus command you run? If so, then the flickering is expected: redisplay due to simultaneous changes in several buffers is not optimized in Emacs, it usually results in all windows on all frames being redisplayed.
