Instagram Images All Pixelated

I'm a regular instagram user and I'm fond of using my ipad air with it. I was casually tapping on images I like when suddenly everything got pixelated. Everything: my gallery, the photos on my feed and everything else! I checked it on my 5s and it seems fine. I tried with ipad mini, too; also fine, Not pixelated at all. I haven't updated my ipad air to ios9 yet, still in ios 8, so I thought maybe the resolution of the app doesn't work properly anymore on the older ios. I installed the update, now in ios 9.0.1. I even re-installed it twice. But all to no avail, everything is still pixelated! So, is the problem with instagram? But why does it work properly on other devices? Is it with ipad air? I tried reporting it to Instagram, still waiting for feedback. Been having this problem for about 12 hours now. Can anybody tell me what's going on? Help, anyone?
