Comment 146 for bug 41301

I had a similar problem last week (maybe the same?). I bought a new mouse 3 weeks ago (logitech usb and wired) that worked nice since then.

Tried with a different login : same problem.
Removed the nvidia proprietary driver, and used the nouveau driver : same problem (+ some refresh problems during scrolling)
Pluging and unpluging the mouse didn't solve the problem. The computer was almost unusable without keyboard navigation skills (which isn't the case for everybody at home).

Note : in Rhythmbox, when the problem occured and the mouse focus was grabed in the list of songs, I saw sometimes the color of the selected song switching to grey during 1 or 2 seconds without doing anything.

With another mouse : same problem
Booting from a USB disk with maverick 32bits (instead of AMD64) : same problem.

Then I remembered there was some parameters in the BIOS concerning USB mouse and keyboard support. My previous mouse was a PS2 one, and my keyboard is still a PS2 one. So these parameters were disabled in the BIOS.

For completness and because some actions may have had an influence in the result (maybe some cold reboot or disabling/re-enabling USB could have correctly reseted the hardware), here are the details of what I did :
1 - I first enabled only the mouse parameter (since my keyboard is PS2) and did a warm reboot. The problem seemed to disappear. But few hours later my wife had once the problem.
2 - I completly shut down the computer to do a cold boot.
3 - I disabled USB in the BIOS and rebooted until login (so no mouse, just PS2 keyboard),
4 - then rebooted into the BIOS, only enabled USB 1.1, enabled both mouse and keyboard USB support, rebooted and played a while to check everything was okay in a session,
5 - then rebooted into the BIOS, re-enabled USB2, rebooted and since then I don't have anymore problems with the mouse.

I don't know why the new mouse worked few weeks with these parameters disabled???

Hope this can help.
