Re: [Pre-PATCH] Overhaul of the LaTeX preview system

From your diagnostic report, it looks like you're using lualatex +
precompilation.  This can cause some issues, but not the ones you report
above so this is interesting.

This is a bug, could you list the steps to reproduce it?

We don't think live previews will be ready or stable enough in time for
Org 9.7, so it is not currently part of the patch set.  It's available
as a later WIP (work in progress) commit on tecosaur's dev branch, if
you are interested in trying it.

This is also a bug, thanks for the report.  I'll look into it.
