Bug: text jumps left and right while typing math when org-indent-mode and linum-mode are enabled. [8.2.5h (8.2.5h-98-g0820d0-elpa @ /Users/kosta/.emacs.d/elpa/org-20140407/)]

Hello,

I've discovered a bug that hinders typing when org-indent-mode and
linum-mode are both enabled. Basically, in certain situations the line
number disappears when a character is added and reappears when another
is added, making the line jump around.

Description:
Open a new org buffer, enable linum-mode and org-indent-mode, and type in the following (the equal signs are
just to delimit in this message):
====
* Test heading
\( x \)
====
Now, when your point is at the end of the second line, press space
twice.

Expected outcome: point moves two spaces to the right, the rest of the
buffer doesn't change.
Outcome: point moves two spaces to the right, while the whole line jumps
back and forth, because the line number of the second disappears and reappers.

NOTE: After some further investigation, it appears this is also related
to highlighting of matching parantheses - If I repeat the same procedure
in `emacs -q`, after entering the closing paranthesis, the opening one
is highlighted for ~1s. When the highlight disappears, the line number
disappears (so there is no need to enter a space to get this). 

NOTE 2: This also happens with regular parens (rather than latex math
ones), but not if they are the first thing on the line.

As a sort-of workaround, I can disable linum-mode for org-mode buffers, since
in those I usually care less about the line numbering than in other
(e.g. programming) modes.
