Hi there,
I am experiencing the same ghosting effect but only when browsing a pdf file in zoom mode.
Reading any book, or page turning any pdf will result in a perfect refresh with no ghosting at all.
But If i zoom in a pdf page, say 200%, and the I browse all the 4 corners of the page, then I can see the ghost effect of the previous page quarter. It is a bit worse if you navigate repeatedly through the 4 quadrants of the page several times, as you can slightly see the superposition of all them in the background.
Of course a Alt+G fixes the problem. This is in a DXG.
I thought it was a defect until I saw this thread. I will sleep better now
