Comment 22 for bug 934770

I'm experiencing several erratic behaviors with the mouse in 12.04 64 bits. Don't know if they are related to this bug report... Should I file another report? Some examples:
1. In libreoffice Calc, if I hover the mouse over the zoom control bar in the bottom right corner of Calc's window, the mouse grabs the zoom control by itself. If I move the mouse left and right, without ever touching its buttons, it drags the zoom control left and right.
2. In libreoffice Calc, if I left-click a tab other than the currently selected one, the new tab is selected as expected, but the mouse behaves as if the clicked button stuck. When I move the mouse after selecting another tab, the mouse cursor changes to the arrow with the little rectangle, as if it was dragging a cell.
3. In Chromium, if I right-click a link and left-click "Open link in new tab", the mouse behaves as if the left-click stuck. When I move the mouse after selecting the new tab, the mouse cursor changes to the little hand grabbing a sheet, as if I was moving the link.
4. In Chromium, if I middle-click a link to open it in a new tab and then left-click the newly opened tab, the mouse cursor changes to the cross with arrowed points (the move window cursor) and the window is restored, as if I started to drag it and let it go right after.

Are these problems related to this bug or should I file another? I'm currently running Kubuntu 12.04 64 bits fully updated.
