That version has reached EOL since a while, so it will not receive

Title:
  compiz loses track of underlying windows when you minimize full-screen
  thunderbird

Status in compiz package in Ubuntu:
  Invalid

Bug description:
  If you run Thunderbird in maximized mode and then minimize it, compiz
  seems to lose track of windows that were underneath. It exhibits
  drawing glitches and you can't select the window with the mouse, even
  with the scroll key, unless you use the unity launcher. Sometimes you
  can't redisplay Thunderbird with the unity launcher unless you first
  select another window, eg firefox.

  This happens both in my main laptop and in VMs and is quite
  reproducible.

  For instance, in the attached screenshot, I had Synaptic (non-
  maximized) running over Firefox (maximized) and then I displayed
  Thunderbird in maximized mode and hit the minimize button. Thunderbird
  minimized correctly, but the Synaptic and Firefox windows were not
  responsive to the mouse, and you can see a line of graphics corruption
  running across from the software centre launcher icon.

  If Thunderbird is not in maximized mode, this doesn't happen.
