Arrangement of elements on a maximized window

I have a window with WindowState="Maximized"(which is also equal AllowsTransparency="True" Background="Transparent" WindowStyle="None"if that matters), and there is an element in the upper left corner of the window Image.

But the actual window.Left position = -8 and window.Top = -8.

So my image is cropped for these values.

I made such a hack to avoid this:

image1.Margin = new Thickness(-this.Left - 1, -this.Top - 1, 0, 0);

but, as you see, it looks weird. What is the correct way to place an element in the real upper left corner of the screen?

I can not reproduce your problem.

Here is what I tried:

<Window x:Class="Test.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow"
        WindowState="Maximized">

    <Grid>
        <Image Source="E:\testImages\test.bmp" Stretch="None" VerticalAlignment="Top" HorizontalAlignment="Left" />
    </Grid>

</Window>

and with this, indeed, the window has a position (-8, -8), which is normal, since this is the way MS Windows "hide" the borders of windows ...
