Is this happening with anyone else? https://www.youtube.com/watch?v=1lWJNB97cy4&feature=youtube_gdata_player
Actually, I can't see this happening on the few apps that I use on a regular basis (iBooks, PDF Expert, Mercury browser, OneDrive).
I've never seen this happen on any iPad and I've had the 2, 3 and the Air. It looks like a hardware problem.
I sent it for warranty later today and they said it might be a display hardware issue and was just a coincidence that it happened after the 7.1 update. Its very strange because I have also searched the web for related artifact issues on ipads and couldnt find anything. Ill get a replacement after tomorrow. Hopefully it will also come with a good display with no yellow tint and bookspine effect.
The yellow screen thread has been quiet for a while so maybe they have sorted that out. Or people are just tired of complaining on deaf ears.
