I´m using Debian 9 (Xfce) and I face a problem with ¨Force Composition Pipeline¨ and ¨Force Full Composition Pipeline¨ settings (NVIDIA X Server Settings).
When I change the default background image and I have these settings enabled then after login my pc stucks (before the background image is loaded). When I have the default background image the pc works like charm.
The workaround solution for me is to have disabled these options and after login I enable them in order to don’t have problem with tearing.
Below there a image with information about my system and graphic card:
