The screenshot was taken in two page mode (horizontically), the issue is only visible then.
When the page is left alone, there is a darker line and light shadow at the center of the screen mimicking a book's binding.
However when turning (especially when using animations where the page can be held mid turn), a large band in the middle of the screen darken while the outer parts of the screen brighten lightly until the page turns completely.
More strangely, as seen on the screenshot though difficult to spot, a smaller darker rectangle also appear around the top left corner of the screen.
