So today I went to use the Square app (and card reader) to accept a payment from a friend for some things I sold him. It got to the signature screen and it looked like this: Instead of the normal signature screen, and when he went to sign it the app just crashed. Well after trying a few times he finally just sent me a PayPal payment instead, but I've been messing around with it at home and I kept repeating the same error. Finally I decided to put my iPhone into Safe Mode and it worked just fine. Which of course leads me to think that it's a Cydia pkg causing the issue. Has anyone else experienced this problem? EDIT: Yay! I figured out which tweak was causing the issue: TVOut2. If I turn it off in SBSettings it works like a charm.
