Hello,
I followed the "Troubleshooting" steps correctly. I selected the same "Layout management & backups" settings.
RDP: The problem seems to be corrected after I resized the fences on the remote PC that I control remotely (RDP) which has a lower native resolution (1680x1050) than my source PC (1920x1080).
Another problem detected: on a PC in 1920x1080 resolution with fences distributed over the entire screen, if I change the resolution to 1680x1050 (i.e. lower), the fences are not reorganized!?! The fences which are at the edge of the screen are therefore no longer entirely visible (cut in two), this worked very well in version 5.05.
Thank you 
Olivier
