Description

  • When Shell navigation/back icon is set via BackButtonBehavior.IconOverride using FontImageSource on Android, the icon renders stretched/squished.
Android iOS

Steps to Reproduce

  1. Deploy ManualMaui to Android.
  2. Open: G Commands > G4 (Shell BackButtonBehavior binding Command to valid ICommand causes back button to disappear).
  3. Observe: the back icon in the top-left is visible but appears stretched when IconOverride uses FontImageSource.

    Hi, @kubaflo! We're re-opening this issue as on the MAUI version 10.0.130, although the G4 back button is not stretched, it is significantly smaller than before:
