Comment 13 for bug 741112

Same issue here, on 2 computers. Both running Ubuntu 11.04 64bit clean install. The dead zones are scattered all over the screen. And when the mouse pointer moves onto them, they stop responding to button presses or wheel scroll. You can easily notice this when using tsclient, as moving the cursor onto a dead zone stops transferring the data to the cursor on the server. This happens in both, Unity and Classic sessions, and turns work with Blender or Gimp into hell... :(
