There is a workaround:

1. Initiate the VNC session, click on shadow man (start)
   -> under search box type in 'desktop' select 'Desktop Effects'
2. Window 'Desktop Effects - KDE Control Module' will appear under
    General Tab, select option "Enable desktop effects at startup"
   which is under Activation
3. Disable (uncheck) all the options under 'Simple effect setup'
   and under "All Effects"
4. Close the vnc session and reboot the RHEL7 box (vnc server)
5. Initiate a new vnc session
