Thanks for the question, I wasn't clear.
Only AA methods 1 & 2 with jitter(b) are affected. The new v3.8 method
3(a) AA is immune to the AA jitter amount issue for certain, but I also
admit I didn't try that AA method with rtr/kla.
This jitter shrinking issue matters more to the povr branch due both
having truly random jitter and in supporting big jitter (>1 values) both
to compensate for another kind of jitter shrink on increasing recursion
depth and for effects. See "Correcting comments on Anti-alias (AA) modes
and jitter" post to povray.general from October of last year for more
(a) - I perhaps missed a fix for the method 3 sqrt of slightly negative
color channel values issue, but to my recollection, that's not fixed in
v3.8 beta 2.
(b) - Even without jitter AA methods 1&2 take additional samples - why I
too had missed that jitter was shrinking to nothing as rtr/kla ran.
Well, and that until I started to play with HDRIs environment maps where
I could run rtr/kla at larger render sizes and good fps rates my
continuous animation window sizes were smallish.
