I have posted an issue on github, but I am asking here too to see if someone can point me to an answer...I have installed jedi-vim and I find it really nice to edit python files. But I came across a problem that I am unable to solve --- it makes editing of LaTeX files much more complex. The problem is the following. I have in my .vimrc: Plug 'davidhalter/jedi-vim'    autocmd FileType python setlocal completeopt-=preview And when I edit a LaTeX file, the $...$ marks that define an inline math disappears unless the line is under the cursor. It's like gvim trying to render the math formula... See: Case 1, cursor in different line of the math formula (the cursor does not appear on screenshot, but believe me...) Case 2, few instant after, cursor in the same line: This make LaTeX files almost impossible to edit. Is there a way to restrict all of the jedi-vim effects to python buffers?I checked that commenting out the plugin line will avoid the problem.  Does anyone know what's happening here?Updateit is a conceallevel problem. If I open a .tex file, I have the following after issuing :verbose set conceallevel?:...which I really do not understand. I checked my .vimrc and I did not find anything that would justify the fact that the python sysntax is loaded for my tex buffers... but it is. Really puzzled. Anyway, adding autocmd FileType tex set  conceallevel=0to my .vimrc solves (hide?) the problem. 
jedi-vim and vim-latex buffers problems?
plugin vim latex;plugin jedi vim
Your problem has nothing to do with jedi-vim.  It has to do with vim-latex using the conceal feature of gVim, where some parts of text are replaced by (supposedly better) graphic representations when you aren't editing the corresponding lines.  In your case a superscript is replaced, but IIRC vim-latex does that with many other things, such as Greek letters in formulas, and various mathematical symbols.  The result depends a lot of the quality of the font you're using.If you don't want that to happen you can set conceallevel to 0:set conceallevel=0(There might be a better / right way to tell vim-latex about that, but with SourceForge still down I can't check it right now).But try it again later with other fonts, you might start to like it.Useful references: :help tex-conceal, :help conceallevel, :help concealcursor.
