I never had a problem with selecting across chunks before I added
TeX-normal-mode to the hook.

If you're having a problem with selecting across chunks, but not with
buffer-local variables being reset (such as RefTeX problems), then you
can hack something up to deactivate deactivate-mark just as I have
done, without using TeX-normal-mode, which is where the slowdown
occurs.
