I filled out SRU justification. Thanks.
** Description changed:
+
+ [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.

reboot
Upon restart at the Terminal:
loimpress -nologo
~/Desktop/BoldTechnicalFontTest/Desktop/BoldTechnicalFontTest.odp
Click F5 the font is not fuzzy.
4) What happened instead is the font is fuzzy.
WORKAROUND: click Tools -> Options -> LibreOffice -> View -> uncheck Use
hardware acceleration checkbox -> OK button -> F5
