Does anyone else notice black lines appearing across an app icons when that app is closed. As the app quits and the phone 'zooms out' of the app, you can see black lines across the recently exited app. Lasts about half a second. I notice it most prominently with Messages. Additionally, does anyone have any info on why you can't select 'never play this song' when using Apple stations by clicking on the greyed out icon, but you can by asking Siri?!
