Running Mint 17.1 with Cinammon 2.4.8 and I have two 2560 * 1440 monitors, both placed in the display settings as next to each other, not mirrored.The mouse cursor moves as normal between the two monitors, except for about 16 pixels from the top and the bottom of the right hand side of the left monitor. Then the cursor just won't move any further right until I move it more than 16 pixels away from the top or bottom of the screen.This is about the height of a panel or title bar, so my first thought was to close all applications and try it with an empty desktop. Still happens. Same with moving the taskbar panel from the bottom.I also tried swapping the displays around but it still happens. Even setting the displays offset so that for example, the cursor coming from halfway down the left screen goes to the top of the right screen or vice versa has no effect; the cursor still gets stuck at the top and bottom 16 pixels of the left screen.Output of xdpyinfo:name of display:    :0version number:    11.0vendor string:    The X.Org Foundationvendor release number:    11501000X.Org
