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. HTH -- http://www.wahlzone.de GPG: 0x49010A040A3AE6F2
