[surya3655]

Description

When trying to draw something using GraphicsView and IDrawable, if the WidthRequest is set to a decimal value like 0.25 or 0.75 and a background is applied to the GraphicsView, a gray line appears on the right side of the view on the iOS platform.

Steps to Reproduce

1. Create a new class GraphicsDrawable that implements the IDrawable interface.
2. Implement the Draw method in the class.
3. Attach this GraphicsDrawable class to a control that requires drawing, such as a GraphicsView. Set the drawable to an instance of GraphicsDrawable, and configure the GraphicsView with the following properties:
4. Set the Background to white.
5. Set the WidthRequest to 498.25.
6. Run the application.
7. You will observe a gray line appearing on the right side of the GraphicsView on the iOS platform.
