Mate 24.04
left-Button will be activated without user intention.
Imagine : Mouse pointer leave above a directory of caja, nothing to do with touchpad, start new action with the touchpad, moving ... leave the touchpad, it leads to drop the directory of the last mouse pointer position. It is not possible without the left-mouse button, but it will be executed by the system. Not all ways, sometimes.
Same behavior on your system, and found a solution ?
I am "sure" it was not present before 22.04, the same behavior for Ubuntu Gnome.
