Automatic rendering makes taking notes from an attached pdf ridiculously hard, especially if the pdf is large. Every time Joplin force renders (it’s every few seconds) the pdf reloads at the beginning instead of the page I was on. In overleaf, R, etc, markdown waits until I tell it to render. This is a much needed feature for note-takers PLEASE! update, I love Joplin but I won’t be able to keep using it if it isn’t fixed.
I think you should create a thread in the support category instead, as this sounds more like an issue than a feature request. You will need to fill in platform, version number, and detailed reproduction steps, to provide more details about what leads to the issue
