I have found that the mouse only works correctly in builds made from Debian-based distros. In builds made from other distros, e.g. Ubuntu (which was once Debian-based), the mouse cursor can only be moved vertically up and down and unfortunately does not move horizontally to the right and left. So, for example, a good build can be made from the installed LMDE 6 distro, but the mouse does not work properly in builds made from the original Linux Mint installation because it is ubuntu.
