Hard to say on this… Once the scrapbooks are dragged in there’s no special “ConDoc” operations happening in the background. They are just LayOut viewports. I would do the usual load reduction on the graphics card. Turn down the edit quality/resolution, turn off auto render. You might even try dragging it into an empty presentation to see if it still acts up. If it does, I would look for something heavy in the scene that LayOut is trying to render. Are there any super heavy objects that LayOut is trying to flatten? Maybe swap it for a 2d graphic/3d object?
