Hi, If it can help :
When I remove all directories, shortcuts and files from the Desktop (Bureau) files, I can run xrandr command without having pcmanfm at 100% CPU. If i just put a new empty directory, I have the bug. If pacmanfm is at 0% CPU in the rendering with two screns, when I copy files to Desktop directory, so pcmanFM hang up at 100% CPU.
