Changes to project don't show on screen - known issue in past versions ?

When I edit a project (i.e. delete a letter/move a letter/delete a node/move the image) it doesn't show the change on screen. I have to zoom in or out and then then it shows the change. Very time consuming to have to use zoom after every change. I see similar forum posts going way back to much older versions of CorelDraw but no solutions. I must ask why this hasn't been fixed if its a known issue. I see suggestions about trying to check/uncheck different boxes in the display options, but no difference. I see some say graphics card issues, but I have tried my both my intel and gtx both with no difference/ old or new drivers. I went thru all the suggestions from corel support; also with no change.
