Hello Michael, or anyone else affected,

Accepted libreoffice into precise-proposed. The package will build now
and be available at
http://launchpad.net/ubuntu/+source/libreoffice/1:3.5.7-0ubuntu4 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from
verification-needed to verification-done.  If it does not, change the
tag to verification-failed.  In either case, details of your testing
will help us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

Bug description:
  [Impact]
   * bold characters blurs horizontally if the font does not have a bold typeface. This makes characters less readable.
     See. https://launchpadlibrarian.net/49398403/Screenshot-OpenOffice.org%203.2-PresentationModeFuzzyFont.png
   * There is a workaround, which is turning off hardware acceleration. But it makes animations and transitions quite slow.

  [Test Case]

   1. type some text and make it as bold in Impress editing mode.
   2. apply font which does not have a bold typeface to the text.
      e.g. "Takao PGothic" font in fonts-takao-pgothic package.
   3. press F5(presentation)
   4. the text blurs horizontally. And the look of the font differs from editing mode.
      See. https://launchpadlibrarian.net/49398403/Screenshot-OpenOffice.org%203.2-PresentationModeFuzzyFont.png
   5. update to -proposed package
   6. the text does not blurs horizontally. And the look of the font is nearly the same as editing mode.
      See. https://launchpadlibrarian.net/49398355/Screenshot-OpenOffice.org%203.0-PresentationMode.png

  [Regression Potential]

  low.
  The rendering way of this part was far from good. This fix is not a perfect solution, but it will improve it.

  1) lsb_release -rd
  Description:	Ubuntu 12.10
  Release:	12.10

  
  2)  apt-cache policy libreoffice-impress
  libreoffice-impress:
    Installed: 1:3.6.2~rc2-0ubuntu4
    Candidate: 1:3.6.2~rc2-0ubuntu4
    Version table:
   *** 1:3.6.2~rc2-0ubuntu4 0

  3) What is expected to happen is when one opens the following at the
  Terminal:

  cd ~/Desktop && wget
  https://bugs.launchpad.net/ubuntu/+source/openoffice.org/+bug/585910/+attachment/1405216/+files/BoldTechnicalFontTest.zip
  && file-roller -h BoldTechnicalFontTest.zip && cd
  BoldTechnicalFontTest/.fonts && sudo mv TECHNICN.TTF /usr/share/fonts
  && sudo fc-cache -f -v && loimpress -nologo
  ~/Desktop/BoldTechnicalFontTest/Desktop/BoldTechnicalFontTest.odp

  Click F5 the font is not fuzzy.

  4) What happened instead is the font is fuzzy.

  First reproduced in LO Maverick 1:3.3.1-1ubuntu3~maverick1, and
  reproduced in Natty.

  WORKAROUND: click Tools -> Options -> LibreOffice -> View -> uncheck
  Use hardware acceleration checkbox -> OK button -> F5
