[regression/8.0.3] Flickering occurs due to padding while navigating pages.

[cropyai]

Description

Hi,

I prepared an example project to describe the bug. The bug happens when navigating pages. The imagebutton component first shows the full scale image without considering the padding property for a couple of frames. Then, the image is drawn correctly considering the padding property. The bug happens in both debug and release mode.

x.mp4

The only code added to the project is:

In the MainPage.xaml:

<ImageButton
    Source="dotnet_bot.png"
    HeightRequest="100"
    WidthRequest="100"
    Padding="50"
    BackgroundColor="Yellow"
    />

In the MainPage.cs:

private void OnCounterClicked(object sender, EventArgs e)
{
    count++;

    if (count == 1)
        CounterBtn.Text = $"Clicked {count} time";
    else
        CounterBtn.Text = $"Clicked {count} times";

    SemanticScreenReader.Announce(CounterBtn.Text);

    Navigation.PushAsync(new MainPage(), false);
}

Other than that, there is another bug with the padding property however it is being tracked in a different issue.

EDIT - Another bug: "When I click previous button to go to the previous page, the imagebutton in the previous page is rendered wrong. It does not consider any padding anymore."

Steps to Reproduce

1. Create a new maui project (.NET 8 Android)
2. Add one imagebutton as described.
3. Add navigation code.
4. Run the project.
5. Navigate pages.
6. Flickering happens.
