Unreal Engine 5.6 Blueprint Android "Display cutout region" error problem

I have a Blueprint project in Unreal Engine 5.6, packaged for Android. When I launch the game for the first time, the “display cutout region” setting works correctly — the left and right notches on the screen are not blacked out.

However, when I close the game and launch it again, the notches suddenly turn black (like black bars appear on the left and right sides).

This causes another issue: for example, the fire button on the HUD becomes unresponsive when I tap on it directly. It only works when I tap slightly to the left of it.

In short, the visual layout of the HUD and the touch input alignment become mismatched.

Is there anyone who can help with this?

  • Show launch image - False
  • Minimum supported aspect ratio.: 0
  • Maximum supported aspect ratio : 2.4
  • Orientation: Sensor landscape
  • Use display cutout region? : True

Did you solve it?

No, this problem persists. Despite all kinds of research, including ChatGPT, Google Gemini, etc., and even trial and error. Even updating to UE 5.6.1, the problem persists.

The game runs normally on Android platforms the first time it’s launched.

This is what happens on the second launch.
