*So, my question is : can I avoid this automatic substitution, and keep the blue (raw) rendering of all the mathematical expressions in Lyx ? (I remark for instance that the image rendering needs some time to be done when opening a document, so I suppose I just have to do something when I load the document, but what do I have to do ?)*
Go to tools>preferences>display and set instant preview to "no maths" (or off).
