Root Cause
When
android:hardwareAccelerated="false"is set in Android applications, standard UI elements switch to software rendering, but WebView may continue using hardware optimization. This inconsistency causes WebView to occasionally render above other UI elements, disrupting the expected visual hierarchy.Description of Change
The solution involves setting the WebView to use the software rendering pipeline by applying
SetLayerType(Android.Views.LayerType.Software, null)when hardware acceleration is disabled. This ensures that WebView aligns with the rendering behavior of other UI elements, maintaining correct layering and preventing any UI components from being obscured.Issues Fixed
Fixes #28902
Tested the behaviour in the following platforms
Note
This issue is specific to Android, as hardware acceleration settings are not applicable on other platforms.
