Thanks!  I can reproduce your issue with a relatively fresh emacs 25 and
org from git.

AFAICS the window gets blanked sometimes in function
org-toggle-latex-fragment of org.el in line

--8<---------------cut here---------------start------------->8---
;; Work around a bug that doesn't restore window's start
;; when widening back the buffer.
(set-window-start nil window-start)
--8<---------------cut here---------------end--------------->8---

A workaround would be to comment out just this line.

I don't know if this is a reliable fix though.
