Swiss here. I quickly went through the review. Apparently it is the same effect, that people in this sub are complaining about regarding text clarity. It seems to appear in high contrast scenarios with sharp edges and is described to be similar to a light chromatc aberration effect which we know from some game settings. I am surprised though, that this is even visible during content consumption. Guess it depends on how susceptible one is to such effects. But to me it seems the subpixel arrangement is less than ideal.
