Multi XScreen configuration ignores theming on all XScreens other than 0.0.

Launching xfce4-settings-manager on the desired XScreen and settings appearance only changes on DISPLAY=:0.0.

Command line is also ineffective.
DISPLAY=:0.1 xfconf-query -c xsettings -p /Net/ThemeName -s "Adwaita-dark"
DISPLAY=:0.2 xfconf-query -c xsettings -p /Net/ThemeName -s "Adwaita-dark"

As for "oddities" it took a lot of fiddling to get things to work. Upon installing once I get the system to not lock up or crash upon configuring more than one XScreen I noticed a lot of "false walls". Windows where locked to small portions of a single monitor and could not be moved around the whole monitor. There were no errors I could find, just a silent conflict with screen dimensions and such. A combination of the xfce4-display-settings, arandr, and the nVidia panel along with a few X restarts finally resulted in windows moving freely through their XScreen/GPU space.
