Earlier, we reported Android 12‘s tendency to crash games when the wallpaper is changed in the background. The bug was first reported in September on the Google Issue Tracker. Now, according to Twitter user Mishaal Rahman, this issue will be tackled in Android 12L.
"…people with automatic wallpaper switchers have found that you can actually crash a game if it happens in the background"
A fix for this is coming in Android 12L. Background wallpaper changes won't trigger theme changes.

Google‘s new UI, the Material You, introduced with Android 12, is a dynamic theming engine that extracts colors from the current wallpaper and splashes it across the system UI and supported apps, giving users greater control than ever over what their phone’s software looks like. Changing the wallpaper in Android 12 results in a configuration change forcing all app activities to restart so that they use the new colors from the wallpaper for theming purposes.
The root cause of this game crashing bug was spotted to be this forced Android configuration changes. Games typically used to ignore such changes but that isn’t the case anymore with Android 12.
This bug, which has remained unsolved for more than 2 months, will now be addressed in the Android 12L. The Android 12L is primarily meant for foldable phones, tablets, and big display devices but will fix many bugs present in Android 12. The fix will ensure that background wallpaper changes will not trigger theme changes or force app activities to restart, preventing crashes. The OS, set to go live in early 2022, will enter beta testing from December to February.
