Stop vim from dynamically updating folds

Question

Is there any way to stop vim from automatically updating folds on the fly? I really love vim's folding, and I prefer having it in syntax mode so that folds are created as I type. But for instance when I code C++ and I write a bracket { it automatically closes all subsequent folds, and when I then close the bracket again with a }, vim automatically expands all subsequent folds, meaning that I have to refold everything.

Another related problem, if I have the same document open in a different buffer, say I have run ":split", then writing an open bracket { will nest all folds in the buffer under the fold in which I opened the bracket, and closing it will un-nest the folds but also close all of them. If I use either "." or "->" to access a member function/variable, it resets all folds in the buffer to be whatever the current foldlevel is, regardless of which folds I have opened/closed myself.

This is somewhat frustrating when I have the same document open in two buffers so I can read the contents of one function when writing another, as I constantly have to switch buffers and reopen my folds.

In my .vimrc I have

set foldmethod=syntax

and that is about it. For autocompletion I use clang-complete and supertab with:

let g:SuperTabDefaultCompletionType = "<c-x><c-u><c-p>"

I think that is everything which migh affect this.
