Current/Missing Behavior

In Windows, opening a window with height and width based on nw.Screen.screens[0].bounds doesn't actually fill the screen. This does work properly in both macOS and Linux.

Expected/Proposed Behavior

When setting a window size to fill the screen, it should fill the screen.

Additional Info

• Operating System: Windows 10
• NW.js Version: 0.77.0
• Code snippet:

nw.Window.open('a.html', { height: nw.Screen.screens[0].bounds.height, width: nw.Screen.screens[0].bounds.width });

Note that these bounds do match the resolution size, but the window that's created is smaller.

how about this?

let bounds = nw.Screen.screens[0].bounds;
let scaleFactor = nw.Screen.screens[0].scaleFactor;
nw.Window.open('a.html', {
    height: bounds.height * scaleFactor,
    width: bounds.width * scaleFactor
});

You can also force the scaleFactor value to be fixed. (#5675 )

@vulcan9 neither of your suggestions make a difference. Scaling was already "1".
