Firmware: 4.8.11090
Bug: popup message leaves behind artifacts

How to reproduce/description:

I've been alternating my Clara HD and Aura One to read The Three Musketeers which is an Overdrive book (epub). When I pick up the one I've not been using I get a popup message saying "New Bookmark" and asking if I want to jump to the location the other device was last at. If I choose "No"* then it re-draws the screen under the popup perfectly apart from where the No button was, there you get sort of half-drawn characters mixed with after image of the No button.

This happened two or three times with the Clara HD but I didn't see it at all with the Aura One which is on 4.8.11073.

Also, I tried to capture a screenshot of this but I couldn't reproduce it once I'd added the line to the conf file to enable this. Maybe the act of adding this feature changes the way the screen is drawn and that avoids the bug. Or maybe I just didn't hit the same set of circumstances.

*I did also see this once with the Yes button - where the "new" location was actually the same as where it already was. Obviously otherwise it would re-draw the entire screen and in that case it's fine.
