Bug - Normal background visual bug

iPhone 6s
IOS 11.3.1

was playing in Peacock’s daily (master difficulty) when the background started looking a bit glitchy
it only popped up when i finished every node except the boss node and showed up when fighting the boss node as well. it fixed itself after i finished that node and checked back at the map

I haven’t seen this as severely but I have had some rogue black pixels appearing in the background whenever I finish a fight on this stage.
