RadialGradientBrush Causes Crash on Android

alfiare · 06 Aug 2025, 23:35

Unity build and deploy on an Android Galaxy S9, the following makes it crash

      <Rectangle Width="150" Height="150" Margin="5,5,5,5">
        <Rectangle.Fill>
          <RadialGradientBrush>
            <GradientStop Color="#FF000000" Offset="0"/>
            <GradientStop Color="#FFFFFFFF" Offset="1"/>
          </RadialGradientBrush>
        </Rectangle.Fill>
      </Rectangle>

I've narrowed it down to the RadialGradientBrush, if it's there it crashes, if not it works fine. I don't have any other RadialGradientBrushes in my project but I've tried a bunch of different versions of this gradient and they all crash.

Does RadialGradientBrush just not work on Android?

Here's the Android Logcat crash...

This seems to be failing inside the Vulkan driver. Could you test building it with the OpenGL renderer instead and see if it also crashes?
If you don't mind, could you please create a ticket in our bugtracker referencing this info so we can track it better?

If I switch to Require ES3.1 and remove Vulkan from the Graphics API list it does work. And confirmed if I switch back to Vulkan it crashes.
