Do you have an issue with moving a window by dragging it across the screen and it suddenly snapping (automatically maximizing) to full screen? If so, you let the top of the window touch the top of the screen and enabled automatic “snapping”. Fortunately, in Linux Mint, it’s a really easy fix.
In Mint 18 Mate (Sarah), go to the main menu, select Control Center, navigate to Windows – Placement, and uncheck the box marked “Enable side by side tiling”.
In Mint 18 Cinnamon (Sarah), navigate to Control Center – Window Tiling, and turn off the slider for “Enable Window Tiling and Snapping”.
