I assume you mean that you see that when you use your .emacs also, so we
know the region face is something noticeable.

So, using your .emacs, the region was active (in the buffer in question),
transient-mark mode was enabled, and the region face is something
noticeable. That's all as it should be.

Dunno. Maybe someone else has a suggestion.
