Mutual Mac

When I either left click and drag to rotate the camera, or Right-click and drag to rotate my character, my system-cursor also moves, and when I reach the edge of my screen, I can't turn anymore.

Edit: In windowed mode, if I try to click and drag, my cursor will snap to the center of the window once every second or so, which also halts the rotation, resulting in very slow and halting turns.

I didn't used to have this trouble.

I'm running Mac 10.12.6.
I tried disabling hardware mouse, and I added Ryzom to the list of programs that can control my computer.
I don't know what the cause is. Any suggestions?

Do you have your mouse inverted?

System > Configuration > Input > Mouse > Invert mouse

There is a cursor bug with this setting on. If it is your case I am afraid you can either disable the option or wait for a fix, unless someone discovered a workaround.

Edit: However I am unable to reproduce the problem I describe above so maybe it was fixed and you experience another issue.

Can you tell us your Ryzom client version? Is it from Apple store, steam or stand alone client?

(client versions are written on various places or you can use /version command in-game)

My mouse is not inverted. I turned it on and off. There's no difference.

I am using a standalone client, Version 3.6.0 (3.6.0)
/version says "FV 3.6.0.9090."
