Comment # 3 on bug 91808 from Martin Bednar

From what I gather, 66067 is about colors & luminosity. I reported this because
of the line that goes vertically through the whole screen. On the screenshot it
is located under "paused". 
The sources of the line are AFAICS the gears just above the spiky area.
Specifying now just to make sure that we're talking about the same thing.
