For me #define MAX_FLUSH_VERTICES 1 fixes the issue. #define MAX_FLUSH_VERTICES 2 is also stable so far. Values starting from 3 result in artifacts.

However, as I wrote in post #150, reverting this:

Solves the problem at all - even setting #define MAX_FLUSH_VERTICES 128 works correct, as well as #define FORCE_FLUSH 0 is also fine.
