Descrizione
Description
On Android If a Graphics View with a requested width and height is used and the content is scaled, the content is rendered outside of the view's dimensions. Additionally there seems to be an issue with text scaling (XAML Live Preview looks fine but on device not). I also observed that on android the render cycle is called infinitely without calling invalidate whereas on windows/ios it is only called once, this is may connected.
Steps to Reproduce
- Clone Graphics view Sample https://github.com/dotnet/maui-samples/tree/main/6.0/UserInterface/Views/GraphicsViewDemos/GraphicsViewDemos
- Open ScaleTransformPage.xaml adjust width and height to 200
- Open ScaleTransformDrawable and add folowing to the start of the Draw method:
canvas.FillColor = Colors.LightGray;
canvas.FillRectangle(dirtyRect);
- Open ScaleTransformDrawable and increase scale to 3
- Observe that the second round rectangle is rendered outside of the view dimensions (gray background)
- Observe that on windows it looks fine
