Disabling Cache
Cache often causes false or outdated errors and/or warnings, as well as sometimes prevents Preview from being updated, which can be very annoying & sometimes make it harder to debug. Is there any way to disable cache?

I don't believe so.
You could see what happens if you set the cache size to 0??
If you do it'd be interesting to know the performance penalty.

Where would I go to set the cache size? In the Preferences->Advanced->CGAL, there are values for CGAL Cache size & PolySet Cache size. Are these the values you are referring to?

CGAL Cache is the one involved in F6 Rendering on the current Release. CGAL cache is the one
affecting errors/warnings.
I have no idea how the newer rendering tech such as Manifold uses cache.
You prob. don't want to zero the Poly cache, you may want to do Design/Flush-cache before a
final/important render.

That probably is not CGAL. But Polyset cache may relate to some funny behaviours using render(),
that a flush helps with.
I just did a quick test using example/advanced/GEB.scad.
A fresh F6 is ~10s, rerender ~0s, flush cache (does both caches) ~18s, CGAL cache set to 0 ~19s,
Poly cache also to 0 ~20s.
A complex model will be very different, particularly without Polyset cache.
