screen shot of vncviewer, the kde start but not working correctly

SUMMARY

I am using nethunter from kali on Xiaomi 8. xfce4 can work smoothly with tightvnc and x11 server, but kde with sddm crashes.

STEPS TO REPRODUCE
1. on nethunter arm64, apt install kde-plasma-desktop, select sddm during installaion
2. edit .vnc/xstartup and add startplasma-x11
3. start vncserver and connect the server with vncviewer on android

OBSERVED RESULT

kde is partly started as I can use the browser to report this issue, but it is not working correctly as no widget or windows appesr.

EXPECTED RESULT

Windows: 
macOS: 
Linux/KDE Plasma: kali nethunter arm64 latest version
