Hi Danne, light is back, so I tried out your build now. But it looks not as expected:
-rewire=old: no red line
-rewire=off, -2+2=no red line
-rewire=off, +0-0/-1+1=red line
-rewire=off, +1-1/+2-2=red line + one white line
-rewire=off, +3-3/+4-4=red line + two white lines
-rewire=off, +5-5/+6-6=red line + three white lines
Moiree looks always identical (better than yesterday, but can't compare to Feb15). But I don't find stair effects.
