           Summary: Mouse randomly acts weird: wrong focus, clicks don't
                    work
           Product: kde
           Version: 4.6
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED

Version:           4.6 (using KDE 4.6.0) 
OS:                Linux

I use a Logitech Mediaplay-mouse and the current NVIDIA proprietary
graphic-drivers and starting (I guess) in January while having KDE 4.5.5
installed I encountered some weird behavior:

- Buttons and mouse-over work in firefox only (might be not related to firefox,
  but that's what I use so often).
- Buttons and mouse-over work in the control-bar only.
- Buttons and mouse-over don't do anything anywhere.
- Buttons act on one specific location only. It's seems even though the mouse
  cursor moves visually, KDE (or X?) uses the same coordinates for the buttons. 
  - Once I could only move an arbitrary window by dragging with the left mouse 
    button no matter where (cursor changed to the according symbol). 
  - Another time a mouse click was always send to a button I clicked before.
  - And then there was a time where I first switched desktops by scrolling the
    mouse while over the desktop and then tried to scroll the contents of a 
    firefox-window but what I got was again switching desktops.
- I just discovered that when I'm stuck with firefox (like in the first item
  above) and when I left-click in a window that is partly covered by firefox,
  that window does not raise nor do the window decorations indicate a focus
  change, but from now on that window receives all mouse clicks (but not the
  keyboard events) and the mouse cursor changes according to the various parts
  of that window.

Mouse-movement is always working.

I think (but haven't tried often enough to be sure) that restarting the
KDE-session helps.

Maybe this bug is related to bugs #257963, #254319 or #173606.

Reproducible: Sometimes
