I'm using VMware Fusion with Linux Mint KDE (I think v13). The mouse works fine except for when I'm dragging something (e.g. resize or move a window). When I do that the mouse moves. Sort of like I click in one place and then it slowly drifts away a few pixels - like it is slowly snapping to a grid.
I don't think it's VMware - the mouse works fine in Windows VMs and in ubuntu gnome VMs. I think it might be some setting in KDE but I don't know what. What can it be?
EDIT
VMware Tools is already installed for this virtual machine.
