Odd peek and hub behaviour, help please?

Theres two weird things happening to my phone lately. First, is the active frame, it randomly turn to become transparent, like when rebooting the phone when still apps open. Second, is when returning to the hub. See the picture. Its kinda good though lol

1. Closed by the OS,
2. Yeah, been there, done that

If only the title of this thread were equally transparent. Then someone could see what the discussions are about without opening up every single one.
