Description Porygon 2019-03-18 23:18:26 UTC
Version-Release number of selected component (if applicable):
libXrandr-1.5.1-7.el8.x86_64
kernel-4.18.0-74.el8.x86_64
RHEL-8.0.0-20190228.1 (RC-1.0)

Steps to Reproduce: 

1. Boot a machine running nvidia binary drivers
2. log into a gnome-shell session with Xorg
3. open a few windows, maximize one or two
4. drag non-maximized windows outside the "bounds" created by the resolution change
5. open a terminal and execute xrandr --output DP-0 --mode 640x480 --panning 1920x1080 (replace output with your actual output, mode should be some low resolution, panning should be monitor's max/native resolution)


Actual results: 

activity bar and maximized windows are aligned with the mode set resolution, panning and dragging a window outside this boundary creates flickering and artifacts.

Expected results:

maximized windows and gnome-shell elements match the defined panning resolution, user is able to pan the smaller mode set viewport around this larger area using the mouse.

Additional info:
tested on Geforce GTX 1050ti (PCI ID 10DE:1c82)
