Thank you for the reply. While that would be somewhat of a workaround it doesn't really address the issue. I want new desktop items to appear on the desktop of the primary monitor as normal as they did with version 3.09, not in a fence.
Do we just need to wait on a new version of Fences that corrects the issue? If so, I have found I can go back to 3.09 via Steam in the meantime, but I am happy to help supply information and test so the devs can come up with a real fix while I have 18.104.22.168 still installed. Please let me know.
