I have also observed it is mostly noticable when in beam show mode, though I see it on some 3d stuff too. debating between software and DMX. don't want to spend a bunch on software that allows things my projector lacks capability for. if one can flex all it's muscles as it were with DMX, I'll probably go that route
I think there may be different "ends" of the green bar of light that are used in different patterns for blending with the other colors. on one side of the bar it matches up, but not the other where the green bar seems to taper off and weaken, so on some smaller yellow parts, or parts I think should be yellow at least, it's mostly red, due to being on the bad side, but other patterns it looks fine. let me try to get some pics of what I'm talking about. it's the "V" beam show pattern with yellow in the spaces between the blue, mine's mosty red in those small parts. also the red circle beam show pattern with small yellow parts in the spaces, again, mine is mostly red.
