• Electron version: (<=)? 1.6.6 - 1.7.2
• Operating system: Windows 10 1703

Expected behavior

The red background color (set as option on the BrowserWindow) covers the whole window on resize.
I remember that behaviour from the last time I worked with Electron. Also noticed that issue in the current VS Code version (1.12.2).

Actual behavior
