It is possible You are doing something wrong. It was pointed you at begining
that it can be floating point accuracy. I think it is possible. Note you used
2048x2048 image so 1 triangle has size about 1/2048 = 0,00048828125. But your
light is at <-30,30,-20>*1e4 and is even further becouse it is area light with
large axes. How many digits is between accuracy of this values ?
As experiment
1. try to remove area_light - is this effect still there ?
2. try to move light closer and wait when effect disappeare.
