After recent update, shading for window snapping appears even when no window is being moved

[Doug Morse]

Hi,

Sometime in the last 24-48 hours, some update has caused Unity / Window Snapping to start appearing, even when I am not moving a window at all. The problem is intermittent, but once it occurs, the only solution is to log off and back on. I have not yet been able to determine what causes the problem.

The problem, more specifically, is that that a large orange box appears if I move my mouse to either the left or right side of the screen, and the box stays there, even if I switch viewports. Terribly annoying and distracting, but otherwise seemingly harmless. It even persists into the Expo view of my four viewports.

The attached screenshot.png file shows the problem on the left side, the right side, and in expo view, respectively.

Going into expo mode and switching viewports does make the undesired orange box go away, but as soon as I move the mouse to either the left or right side of the screen, the orange box comes back again. Logging off appears to be the only way to fix the problem.

The problem does _not_ seems to occur if their is no visible window in the viewport when the mouse is moved either full left or full right. The problem _does_ persist, however, once it has occurred and I switch to another viewport without any visible windows.

Just to repeat for clarity: These problems occur simply by moving the mouse to either left or right edge of the screen; I am not moving any windows by any method, nor is any mouse button being clicked and/or held when this occurs. This problems was _not_ occurring after I initially upgraded to Oneiric from Natty -- the problem started only in the last day or two (I have been updating daily).

Hope this helps.

Thanks,
Doug
