Gosh, I just turned off my iPhone and didn't notice any graphics corruption. Should I schedule a visit to the Genius Bar? 
Seeing that pretty much everyone is seeing this "issue" (at best it's a small inconsequential graphical glitch), it doesn't seem like any reinstalling or anything like that would make a difference.I have the same issue with an ipad mini.
Do you think that format the ipad can solve this issue ?
Thank you very much
As in not fixed in 7.0.4? Something like this is of such low priority and even severity that it might get fixed at some point, but it's likely that no one is really going to go out of their way to fix it for some point update which are often for more critical/bigger fixes.wtf apple, this bug is not fixed and more...
