If you look at the link I suggested, it appears to only affect the reader when turning pages; it's as if, when the screen refreshes, that something interferes with the cels, causing them to not fully turn on unless the UV (or whatever else is in the direct sunlight) is blocked. It doesn't appear to be a defect, since it only showed up with the PRS-505, and Kindles also seem to have the same issue... so it's due to something with the Vizplex sheets. Given the descriptions of the electrophoretic process, the idea of energetic photons causing the cell to turn 'off' when it should be on (and only during the drawing process) seems like a likely hypothesis.
