The Windows snapshot doesn't look right. If SetBlur(10) is used on the canvas, I expect the specified radius (10) to be visibly blurred. I believe this works correctly on Android. So either this is a bug on Windows, or I might be mistaken.

@PureWeen @bhavanesh2001 As per the current implementation on Windows, the GaussianBlurEffect only supports applying blur to the entire visual content, as documented here: https://learn.microsoft.com/en-us/windows/win32/direct2d/gaussian-blur. Therefore, the current output image on Windows is expected and aligns with the platform's behavior, as there is no available API to apply the blur effect selectively based on corner values.

Shall we proceed with the current image? Please share your thoughts or concerns.

@anandhan-rajagopal Keeping the snapshot doesn’t seem right to me. The expected behavior is that the blur should be applied within the specified radius. Windows not supporting that directly is more of a limitation we should handle, not something we should lock in as the correct output.

maui/src/Graphics/src/Graphics/IBlurrableCanvas.cs

Lines 3 to 6 in b43b974

	public interface IBlurrableCanvas
	{
	void SetBlur(float blurRadius);
	}

Hi @bhavanesh2001 , Thank you for your feedback. For now, I have decided to consider the Windows issues separately and have excluded Windows from the test case accordingly, along with linking the relevant issue report
