Emacs -Q
C-u 20 SPC RET RET RET RET ; type some random whitespace
M-x global-whitespace-mode
M-x whitespace-mode
M-x whitespace-mode
The last command should toggle local whitespace-mode off, but note that the
whitespace display characters are not properly removed from the current
buffer.
I had a look at whitespace.el and I think the problem lies in
`whitespace-display-char-on'. Among other things, this function stores the
buffer display table and replaces it with a temporary display table to show
whitespace chars. The original is restored when the mode is turned off.
However, with global-whitespace-mode active, there is already a temporary
display table in place, which whitespace-mode incorrectly picks up and stores,
clobbering the original display table in the process. When whitespace-mode is
turned off, it restores the temporary display table set by
global-whitespace-mode, which leads to the problem.
Here's a little patch to check if global-whitespace-mode is active before
storing the display table. I've tried this for a few days with no obvious
problems.

Did you try running whitespace-tests with this change, and if so, did
they pass?
If the tests pass, would you mind to please add a new test for this
bug?
Thanks.

Yes, all tests pass.

I've written a new test and confirmed it catches this problem. I also
tweaked the original patch to handle another instance of the same bug.
Patches for whitespace.el and whitespace-tests.el are attached.

Thanks, pushed.
A couple of notes, for the future:
. The test at first failed for me, and needed some tweaking, because
whitespace-mode refuses to turn on in batch mode. I guess you ran
the tests in interactive mode? You should run tests in batch.
. The patch was not applicable without manual editing, because it
used file names like whitespace-a.el, which don't exist. Please in
the future submit patches produced against the correct file names,
preferably with "git diff" or somesuch.
. Please include with the patch a ChangeLog-style commit log message
(see CONTRIBUTE for details).
. Finally, this contribution exhausts the amount of changes we can
accept from you without legal paperwork, so I encourage you to
start the paperwork rolling, for us to be able to accept your
future contributions. (I can send you the forms off-list if you
want.)
Thanks again for working on this.

Sorry, yes, I did. I read about batch testing in the manual, but didn't
click that most tests need to run that way. Of course they do, now that
I think about it.

I'd like to keep contributing where I can, so please do send the
paperwork when you have a moment.
Thank you for the feedback and for fixing up the code. It is very much
appreciated!
