OK, now on my 3rd rMini with this issue. ** Warning... if you look for it and see it, you will not be able to "unsee" it! ** Most noticeable on full brightness and on blues / greys, and only in landscape mode. For example, in the settings screen when an option in the left pane is selected and blue. Look at the blue (right at the edge), look away and look back.... see faint lines for a split second before your eyes adjust. Can also be visible when scrolling and then stopping. Also visible on the dock at the left edge or right edge, again whilst in landscape. Same effect. And... landscape keyboard on grey shift keys either side os the screen. Anyone else? Or am I just very unlucky or just hyper-sensitive to this?
