Yep. My iPad mini 4 has been perfectly fine until two DJIgo updates previous. The second to last update started the, "High cpu' message and then the last added artefacts, green and black, to the viewing screen. Fix? I bought a 2018 ipad and now everything is fine. Typical.
P.s. There's no anti-glare added to the latest ipad so think twice as I should have gone for the 1st gen iPad pro.
