Copy/pasting large images is very slow

Is your feature request related to a problem? Please describe. Copy/pasting a few large images from one diagram to another takes a weirdly long time (10+ seconds per image).

Describe the solution you'd like Faster

Additional context If I take a screenshot and paste it into a diagram it shows up instantly. Which makes me think the problem is with the code rather than size of the images.

I added the following to Extras -> Configuration because I only use the desktop app in offline mode and want to use large images.

{
  "compressXml": false,
  "maxImageSize": "10000",
  "maxImageBytes": "30000000"
}
