Maybe I'm missing something, but won't your suggestion effectively
replace the background rendering of man pages with fully synchronous
one?

The usual way to fix these problems is to set Man-width to a non-nil
value, as appropriate for your frame/window dimensions.  Would that
solve the problem for you?
