[Bug 585910] Re: [Upstream] Impress Font fuzzy in presentation mode when Use hardware acceleration enabled

[Nobuto MURATA]

Hi Benjamin,

> java.lang.InternalError: Can't connect to X11 window server using ':0'
as the value of the DISPLAY variable.

With unsetting DISPLAY variable for pbuilder, i.e. skipping whole X
related tests, the package seems  buildable. But I will try to confirm
that in my local environment.

pbuilder with DISPLAY viriable is discussed in:
Bug #816556, Bug #815483
http://lists.debian.org/debian-java/2012/11/msg00004.html

In the past example Bug #815483, the package is accepted if it can be built in PPA. But unfortunately LibreOffice cannot be built in PPA due to "no space left on device" during build.
It's mentioned in Bug #1064962.

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.

  [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

          500 http://archive.ubuntu.com/ubuntu/ quantal/main i386 Packages

  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
