Double mouse cursor on desktop

[ghost]

Archlinux x64, hawaii-meta-git from AUR;

After entering the desktop by execute "hawaii-session", the mouse cursor works fine;

Whenever I open a GUI window application, the mouse cursor becomes two stacking together: a white bigger one stacks on a black smaller one. If I move the cursor I can see the black one is following the white one, and it never vanishes even I close all the GUI window.

After the second one appears, pinpointing the cursor becomes very difficult.
