Log out and back in.

KDE wrong cursor theme in application "nomachine"

Try clearing out your cache directory. Log out of Plasma completely, hit Ctrl+Alt+F3 at the graphical login screen, then log in at the character mode console, and issue the following command… rm -rf ~/.cache/* Press Ctrl+D to log out, and Alt+F1 to return to the graphical login screen. Log in again and see if it makes any difference.
