I use Azenis. It's a animated one that's not too animated. You can find more at gnome-look.org and clicking on x11 cursor themes.

i use Bibata Rainbow the small and beatuful cursor with color changing animation

Feel free to select any one you like X11 Mouse Themes

I have installed Polar Cursor Theme from KDE-look.org, a kind of minimalistic cursor theme with KDE touch. But I am using this cursor theme on Xubuntu for myself.

For the loading animation, the cursor changes to a spinning disc with a colored slit (orange, blue or green for choices), like slot screw drive.

I recommend this cursor theme for minimalists whom wanting to have cursor with beautiful KDE theme touch, minus the distraction (of bouncing cursor).
