No, this is a change in Parallels behaviour since 1970. In 1970 if your OS Window was off the edge of the screen and you toggled between OS Window and Fullscreen and back to OS Window the OS Window would stay the same size (1920x1200)... in 3188 when you toggle back from Fullscreen to OS Window mode the OS Window is resized so it fits on the screen... and hence moves all your icons. Auto Arrange is disabled.
Also in 1970 it remembered the size of the OS Window or Display Mode (Fullscreen) when starting up... so it always remained at 1920x1200.
