**Expected Behavior**
I would like to see the window move across the screen.

**Actual behavior**
The window moves around the screen. But first, the height of the window decreases.

**To Reproduce**
Write simple program that contains code:
`
mainWindow = new BrowserWindow({ width: 370,
		height: 270,
		x: 100,
		y: 100,
		resizable: false,
	 });
`
Start app. Grab the window with the mouse for its title and drag across the screen.

**Additional Information**
This error occurs when explicitly specifying the x, y coordinates of the window and the option "resizable: false".
