Screen flickering blue on iOS phones

Working on a 2D card game in Unreal for iOS. When the game is launched on iOS the screen flashes blue only for the game map. The screen doesn’t flash blue in Unreal or in mobile view but only on iOS.

This wasn’t a problem in earlier iOS devices. (Currently using iOS 12.2)

Not sure why this is happening, Don’t know if it is our code since the problem doesn’t appear in the editor.

Thanks!

Check your post-process setting. We had one problem with Auto-Exposure being set to “Auto-Exposure basic” and got huge flickering in 4.22. But really try disabling screen effects, light effects etc. It is not much but usually it is one setting that causes such screen space glitches
