If you select  a drawing in the model window and you COPY it, as you Drag the Copied drawing to another point on the page it is very slow to update or refresh the screen, especially when you are trying to see where you want to drop it, everytime you adjust your position of where you are about to drop it, the copied image disappears.

ACADLT 2006 had this issue, but they have a command "DRAGP1" or "DRAGP2" which adjusts the refresh rate.  Mine came default set at DRAGP1=50, after adjustiing to DRAGP1=1000, it was smooth as a whistle.

Inistailly I thought it was a Slow PC, but I have a QUAD Core HP Workstation which is very quick, so i didnt think it was this.

Can this be adjusted in DraftSight??
