We are experiencing significant performance issues with the eraser tool when working with heavy diagrams, particularly complex ER diagrams, on our canvas. Initially, navigation within the diagram feels sluggish, and we have observed that the fonts within the diagram sometimes blackout. Eventually, the entire page blacks out, necessitating multiple refreshes just to restore visibility of the diagram.

To maintain a smoother experience, we have resorted to splitting large diagrams across multiple pages, although ideally, these diagrams should reside on a single canvas for ease of management and visualisation.
