Object(s) outline is not displayed while using commands like Copy, Move, Rotate etc. the most likely reason for this behaviour is the current setting of system variable DragMode.
Below is taken directly from the AutoCAD Online Help File [F1] -
DRAGMODE System Variable
Saved in: Registry
Initial value: 2
Controls the display of objects being dragged. When Drag mode is on, AutoCAD shows the image of an object as you drag it to another position. With some computer configurations, dragging can be time-consuming. Use DRAGMODE to suppress dragging.
0 Does not display an outline of the object as you drag it
1 Displays the outline of the object as you drag it only if you enter drag on the command line after selecting the object to drag
2 Auto; always displays an outline of the object as you drag it
You can draw new objects dynamically and drag them into position on the screen. You can also drag existing objects with many editing commands. With some computer configurations, dragging can be time consuming. Use DRAGMODE to suppress dragging.
Command line: dragmode (or 'dragmode for transparent use)
Enter new value [ON/OFF/Auto] <current>: Enter an option or press ENTER
ON -> Permits dragging, but you must enter drag where appropriate in a drawing or editing command to initiate dragging.
OFF -> Ignores all dragging requests, including those embedded in menu items.
Auto -> Turns on dragging for every command that supports it. Dragging is performed whenever it is possible. Entering drag each time is not necessary.
