I've had my rMini since Dec 3rd. After going thru several, the screen on this one was perfect. I've experienced screen interlace/flicker on my Gen 1 mini back last year when I bought it, and an iPhone 4. This rMini deffo didn't have it. So, as I said the rMini screen was perfect. However after installing 7.1b2 I've noticed interlacing in part of the screen. Noticed it most in the bottom left of the dock when in landscape with home button on right. I've restored back to factory, and DFU restored to 7.0.4 as a new device, but the interlacing is still there. Any ideas?
