[Bug 758253] Re: unity-compiz develops focus problems and sends input to minimized windows when 'Keep previews of minimized windows' is enabled

 

Since this bug report is too old and is related to a plugin that is not
enabled by default on the desktop I ll change the bug status to Won't
Fix. In any case, if you experience the same issue in one of the
supported Ubuntu releases, feel free to re-open the bug and update the
description, so that we add it in our TODO list.

** Changed in: compiz (Ubuntu)
       Status: Triaged => Won't Fix

** No longer affects: compiz

Title:
  unity-compiz develops focus problems and sends input to minimized
  windows when 'Keep previews of minimized windows' is enabled

Status in Unity:
  Invalid
Status in compiz package in Ubuntu:
  Won't Fix

Bug description:
  Binary package hint: unity

  Recently unity-compiz has been getting itself into a state on my PC
  where it loses track of windows, with the following symptoms:

  a) Without being prompted, it decides that a particular window is
  'always on top'. If you click on another application, the original
  window stays on top.

  b) Even if you minimize this window, input is still sent to it when
  the mouse is over the location where the window last was seen.

  So if for instance the window mistakenly 'always on top' is gnome-
  terminal and there is a firefox window open, if I minimize gnome-
  terminal so that only firefox is showing, when I move the mouse over
  the section of firefox that was formerly covered by gnome-terminal,
  the mouse cursor turns into a 'typing input' cursor, and I can't click
  on links etc in firefox, and that part of firefox becomes unusable. It
  doesn't have to be firefox - for instance, I had the problem in apport
  and I couldn't click on the 'Send' button because the input was being
  sent to the minimized window.

  If the window 'always on top' is nautilus and it is minimized, when I
  move the cursor over its former location in say firefox and press the
  right mouse button, I get the nautilus popup menu.

  Closing the 'always on top' window makes the problem go away but then
  compiz often mysteriously chooses another window to be 'always on
  top'.

  This has been happening more and more frequently. I am also using the
  unity desktop more heavily now by opening more windows at once.

  I have been running a natty VM in VirtualBox at the same time as
  running natty in the host (where I am seeing the issue) in case that
  makes a difference.

  Any suggestions on how to debug this further?
