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

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Ritesh Khadgaray (khadgaray):

[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.

Binary package hint: openoffice.org
Binary package hint: libreoffice

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

     1:3.6.2~rc2-0ubuntu3 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
