Fixed in 26.3-snapshot-7.
Addition: in oit_sampple.glsl, between lines 17~20, this multiplier is wrongly applied after the first use of depth
depth
float scaleCoeffAddend = (currentAbsorbance * -depth) + currentAbsorbance; scaleCoeff -= scaleCoeffAddend; depth *= float(COEFF_COUNT - 1) / COEFF_COUNT;
