Right mouse menu not usable

[EricDHH]

Oneiric beta amd64, fresh firefox with this bug from today!

Like in 785195 the right mousebutton menu disappears when the mouse was moved in any way. It is not possible to use any of the menu entrys with the mouse. This was okay until the today update.

Status changed to 'Confirmed' because the bug affects multiple users.

Happens randomly here since pre-alpha and not for a while since beta2, but just now again. Maybe it's related with OpenGL sync_to_vblank, which I've disabled now. Workarounds can be switching workspaces, click on top panel, open and close bookmarks, navigate with arrow keys.
Issue is known since Natty. bug 785195

Attached current xsession-errors.

Happens always here, if i want to move to /mnt i have to enter this by hand. The left button is inactive and did not work. Have placed the pointer to the inactive piece.

Disabled OpenGL sync_to_vblank didn't help.

Eric, #4 is about Nautilus, but the issue was reported against Firefox. Please explain the relation, thanks.

Oops wrong bugreport, for me this bug was fixed with the latest updates.
