Flickering screen when using G-SYNC option in Nvidia with Compositing on.
When using "Allow G-SYNC/G-SYNC Compatible" with Xfce Compositor enabled the screen will turn off and on consistently. If "Force Composition Pipeline" is on in Nvidia, the problem stops. Also If disable either G-SYNC or compositing problem will stop. This problem does Not happen with other desktop environments just the Xfce Compositor (xfwm4).
