Do you mean this change?

        * src/term.c: The code was disabling all mousing and mouse events
        during multiplot.  

It only affects multiplot. The transparent_solids demo does not use multiplot.
So I do not understand how this change could affect the demo.

Perhaps it is a failure to explicitly initialize some variable, and after rebuilding 
that variable happens to get a different starting value?
