[Solved] Game started to look like a mess on Android 8+

Hello!

I have an app on Google Play and it was working fine on Android 6-9 before Google’s requirement to update it to 64-bit version. After updating my app started to look like a mess on most of Android 8+ devices.

This is how my app looks like on Android 6-7 (the way it supposed to look):

And this is how it looks like on Android 8+ devices (a total mess):

I have tried Unity2018.3.4, Unity 2018.4.12f1 (LTS) and the latest 2019.2.16f1. All with the same result.

These are my build settings (target API is 28 for Android 9):

Does anyone know what might be the issue? Any help is appreciated!

Solved the problem: assigned background image to canvases used in scenes.
