OMV-Remotedesktop-lag-disorder

[Neo2018]

Hello,
I desperately need a Remote Desktop in OMV OpenMediaVault.
Installed> OMV-Extras> Plugins> openmediavault-remotedesktop 4.0.1
Connected via Windows Remote Desktop Connection.
After a few clicks, no reaction, connection reboot few clicks and again lags / errors.

Code:

root@rockpro64:~# uname -a
Linux rockpro64 4.4.138-1094-rockchip-ayufan-gf13a8a9a4eee #1 SMP Thu Aug 9 20:29:55 UTC 2018 aarch64 GNU/Linux

Remote Desktop is very important to me.
Please help.
