Description

I've painted three RadialGradientBrush objects in Frame objects:

  1. Upper left - center (0.0, 0.0).
  2. Center - center (0.5, 0.5).
  3. Lower right - center (1.0, 1.0).

On iOS, the three gradients are painted correctly.

On Android, no radial gradients are painted.

On UWP, only the center radial gradient is painted correctly.

See the screenshots below.

Steps to Reproduce

  1. Run the attached sample.
  2. Browse to the radial gradient brush demo page on iOS, Android, and UWP.

Expected Behavior

Three correct radial gradients - upper left, center, and lower right.

Actual Behavior

Three correct radial gradients on iOS. Zero radial gradients on Android. One correct radial gradient on UWP.
