Overlay will disable Nvidia G-Sync

[zzonez]

If you have an app that is running in g-sync mode and attach an overlay to it, g-sync will be disabled.

You can quickly test it, if you change the electron-demo.ts and make it attach itself to poe.

overlayWindow.attachTo(window, 'Path of Exile')

I don't own G-Sync monitor to test. It is very unlikely that someone else will investigate this. 😄
