Mmmm. I see this also.

The cause of this lossage is the value of 'window-start' for the various
gnus display buffers when certain things are done -
'delete-other-windows' for a start.

XEmacs seems to optimize this such that the value is not up to date for
what *should* be in the buffer at the time of the various calls, rather
what *was* there prior to the action.

The DOC for 'delete-other-windows' notes that 'window-start' should be
set to something sane before calling.

I think. This is as far as I got looking at the issue, and that was a
few weeks ago now. Ain't it grand when life is *so* full? :/

Hope that helps someone find this,
