Comment 6 for bug 875557

Since my report, Bug #877951, has been marked a duplicate of this bug, I just thought I should mention the following:

1. The procedure for creating the problem as reported by the OP in this report (Bug #875557) does NOT cause the problem for me. In other words, clicking on the viewport switcher in the launcher and then moving the mouse to the left does not cause the unwanted orange box to appear. Indeed, on repeated trials, even trying other edges when in expo view of the viewports does not induce the orange box. However, I have set the middle mouse button in Compiz settings to bring up expo view, and when I access the expo view in this fashion, moving the mouse to the left or right edge in expo view OCCASIONALLY induces the orange box.

2. Relatedly, the unwanted orange box most often appears for me when NOT in expo view; simply moving the mouse to the right or left edge of the screen can induce the problem. I have not yet been able to determine under what conditions this happens and why it does not occur at other times. The problem does seem to be a "state" issue, in that, once it occurs, it keeps occurring until some sequence of events brings it out of the unwanted state of behavior. I most often go into expo view and click a different viewport and then back again to the viewport within which I was working in order to get rid of the orange box. Sometimes this fix takes right away, other times I might have to go into expo view to fix it repeatedly to get the unwanted behavior to stop (for a time; the unwanted behavior invariably returns, typically within 10-20 minutes).
