May be there is a problem with your template. Save your project and close it then (File>Project>Choose Template) then open the file (File>Open>Project) you were working on see if that works.

I believe this is related to monitors and Graphics display, some fix it using an adjustment to the Zoom option or changing from duplicate to Extends Displays.

The thread below has some additional tips
