Black screen on Google Pixel C

Our QtQuick Android apps just show a black screen on Android. This also seems to affect other Qt Android apps on the Play Store including VPlay stuff. A fresh, empty, project is also affected. For some reason the Qt Everywhere demo on the Play Store is not affected.

The splash screen of the app is shown but then only a black screen is rendered. The app is clearly running as indicated by debug output and the app can be blindly interacted with; all QtQuick contents are rendered black however. There are no warnings on the console that could give a clue about why this happens.

We could not reproduce this issue with devices other than the Google Pixel C
