Description

At various (seemingly random) times during a session, a window will suddenly jump and start moving when all I've done is left-clicked on it with the mouse to make it the active window. It will behave as though I've held down the Alt key in order to move a window, but I haven't touched the Alt key. To stop the window from moving with the mouse, I click again, then I usually need to move the window back where I want it by the intentional methods (i.e., dragging by the title bar or pressing and holding the Alt then dragging the window).

It has happened if I've clicked on the title bar and also when I've clicked somewhere in the window.

This has happened on several PCs, including a Dell laptop, a Toshiba laptop and a whitebox desktop PC, all running Xubuntu 12.04 LTS with xfwm4, version 4.8.3.

Version: 4.8.3
