SUMMARY

I just tried rdpserver for the first time (krdp x86_64 6.1.5-1.fc40) on wayland and it worked fine until I tried to paste content remotely and the connection froze.

STEPS TO REPRODUCE

Installed with:
```
sudo dnf install krdp-server libva-nvidia-driver
```

After this, remote desktop showed up in system settings. I added a user and connected with `remmina 1.4.33` from another fedora 40 machine. It worked fine until I pasted text copied remotely into the window (copy/pasting within the window worked fine). I tried a couple of times and it seems consistent.

OBSERVED RESULT

Connection freeze

SOFTWARE/OS VERSIONS

Environment: Fedora 40 (KDE spin), freshly installed today
nvidia driver installed via `akmod-nvidia.x86_64 3:560.35.03-1.fc40`
kernel parameter `nvidia_drm modeset=1` set
remmina 1.4.33 (rdp client)

ADDITIONAL INFORMATION

Here are the logs from `journalctl -b | grep -i 'rdp.*]:`

```

Side note: Running `krdpserver -u user -p test` from an ssh connection didn't work. I think that was because it wasn't a child process of the wayland login shell. After generating a SSL cert it would run from within Plasma, but the connection wouldn't render anything. I had to configure the server through system settings before it'd work.

Clipboard behaviour has changed in 6.5. 
Can you test again with Plasma 6.5 and reopen if an issue persists.
