Re: frame-local variables weirdness

[Richard Stallman]

    I think someone more experienced in that part of code would have to
    debug this. Apparently, with the patch applied the local variables
    (keymaps, font-locking, etc.) are bleeding from one buffer to another
    and Emacs turns quite difficult to use.

Does this include variables which have no frame-local bindings?
(It sounds like that is what you mean.)
