For the antialiasing problem note that neither v3.1 nor v3.6 handle
it properly. They both have problems.
  The antialiasing used in v3.1 doesn't work correctly when there are
ultrabright but very small (sub-pixel) details. The v3.6 antialiasing
doesn't work correctly with ultrabright larger areas (over pixel size).
The latter was a "fix" to the former, but it only introduced another
problem, so it wasn't really a solution.

  In the vast majority of cases the older antialiasing gives better-looking
results than the newer. AFAIK some kind of new method (perhaps similar to
the tone mapping in megapov) which would fix both problems is being studied
for v3.7.
