Unexpected viewport location using monogame

I'm having an issue with viewports not appearing where they should. Two viewports appear a good 10 pixels below where they should be. I created a very simple test project that does nothing more than place the viewports and draw a texture in each. I created this in both monogame 3.0.1 and XNA. I only encounter this issue in monogame. In XNA, it works fine.

I tried to post screenshots, but I'm a new user so I'm out of luck there. The top is exactly where it should be. Everything else is shifted down 10 pixels. Does anyone have any thoughts on why this is happening and how to fix it? Thanks!

Here is the code:

    Texture2D _bottomTexture;

    public Game1()

        graphics.ApplyChanges();

        // stretches across the top of the screen. 
        // It starts at the top left corner (0,0), is 1024 pixels wide and 28 tall

        _rightViewport = new Viewport((1024 - 37), 28, 37, 700);

        // Stretches across the bottom of the screen
        // it starts at the bottom of the left and right borders on the left edge of the screen
        // The starting Y coordinate would be the height of the top bar plus the height of the side bars: 700 + 28
