Even if it was 2GB of some data? Even if you run low on memory?

TFA and comments are clearly a solution is search of the problem.

Is it possible to copy 2GB of data to the clipboard? If it's an image or something I'd expect the clipboard to contain a reference to the image or some such. How do clipboard managers handle this?

		Yes. It contains a reference to the image in the source application. When you paste, X or Wayland lets the source application communicate with the destination application to send the image over. You’ll likely always have a very simple clipboard manager that stores a single copy of the clipboard so you don’t rely on the source application staying alive. Clipboard managers are free to store the clipboard anywhere.
