[Bug 1640717] Re: Software Updater input events go to the wrong control

[Ubfan]

Ubuntu 16.10, plain install on UEFI machine, Nvidia Quadro 1000M running
nouveau driver displays this problem. In addition, when the install is
requested, both the downloads output and the subsequent terminal/text
output are reduced to just one line, regardless of the size of the
window -- resizing does not affect the one line (it does not expand).
See 838973 askubuntu question (unanswered) for screen shots of this
problem.

Title:
  Software Updater input events go to the wrong control

Status in update-manager package in Ubuntu:
  Confirmed

Bug description:
  When Software Updater starts, the "Details of updates" section only
  covers half the window's height, even though the "Technical
  description" section is collapsed. Refer to attached image #1.

  If I expand then collapse "Technical description", the "Details of
  updates section" restores to normal look, as in attached image #2.
  However, the lower part of the section (below the selected row in
  image) is not functional and does not respond to click, scroll or any
  other mouse activity.

  Input events instead go to the hidden "Technical description" section,
  for example you can change from its "Description" tab to its "Changes"
  tab by clicking on the checkbox two rows down from the selected one in
  the "Details of updates" section. Also the mouse pointer changes to a
  text pointer in the area that would have been covered by the text box
  if the "Technical description" section had been expanded (as in image
  #3).
