I run the XFCE Desktop with a dual monitor setup. I have the second display X and Y scale set to 1.100000 using the xfce4-display-settings gui Scale:Custom feature.
After this update, I was not able to login to my user account. The problem symptom is a LightDM infinite login loop. With the correct password the system tries to do something, but finishes the effort back at the LightDM login prompt. Using the console to access journalctl, the actual fail indication is that XORG dumped core.
If I use nano from the console to edit ~/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml and set X and Y scale to the default 1.000000 for my second display, and then reboot, I am able to login to my user account. Once I am logged into the XFCE desktop if I attempt to set a custom display scale for my second display using the xfce4-display-settings gui Scale:Custom feature, XORG dumps core and sends me to the LightDM login prompt.
