I picked up this iPad Pro about two weeks ago. And today while I was writing in Goodnotes I realised that there was a 'rippling' effect that was happening in the bottom centre of the screen (portrait mode with Face ID module facing up, slightly above and to the left of charging port). It didn't require much pressure to see the issue happening, I just write how I would normally write on a piece of paper, and just to let you guys know, I am not a heavy writer by any means. In fact, the same issue can be replicated just by applying pressure with your fingers, it does require a bit of pressure (about the same amount of pressure you'd press for a 3D Touch on some older iPhones), but definitely not anything excessive. What worries me is that this does not happen anywhere else on the screen except that one spot, and I'm not even pressing on the spot, it's around the region. I do have a glass screen protector on. I have attached a video demonstrating the issue, the first half is the issue with just pressing and the second half is me writing.Please let me know if this is a hardware defect, and is this happening to any of you guys?
