Just s general warning, it doesn't say anything about your observations.

Be careful with drawing conclusions when using vnc. The past year I've been working remote and I'm using vnc to access my desktop at work. Transferring clipboard data most times work, but sometimes it is a pain. It won't copy or paste the right selection. Reconnecting vnc usually solves the issue.
This is independent of the source or target application.

So the issue you observed might be caused by vnc or it might be indeed an issue in Lazarus
