Since the last update, I have had really bad issues with copy + paste within XD. It severely lags the application and the mouse input becomes sporadic, causing items to move around. This only occurs with copy and paste (both keyboard shortcuts and edit menu), not option + drag.
I initially thought it was my system but this does not happen elsewhere (I have not had any issues with Figma) and I have tried reinstalling XD but that has not helped. It also happens on multiple files so I think this is a bug with the software. I am on an M1 machine (running through Rosetta 2) but I have not had issues before so I think there may be an issue with the current version.

Sorry for the delay in resolution. I did test this on my end and was unable to reproduce it. I'd recommend updating XD to the latest version and check if it still happening. If it still happening, please confirm if you are using an apple magic mouse?
