Description

I have a FHD and a 4K Monitor connected to an NVIDA-proprietary driven card.
FHD ist connected with DVI and 4K is connected with Display Port.
From the BIOS point of view, the FHD Display is the primary display, but I set the 4K display within Cinnamon 3 and within NVDIA settings as the primary display.

In both Mint 18 and Manjaro-Cinnamon, after the screen saver / lock has been activated and then I return to my session by re-entering the password, open windows are moved from the 4K ("virtual primary") desktop to the FHD ("virtual secondary") desktop.

I expected to find all windows at their original place - as is the case with long-used Mint 17.3.
