Comment 13 for bug 846381

As in upstream bug on launchpad:
https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/846381
Letters of Fontwork such as 'O' appeared coloured in on slideshow mode, if they use gradient or bitmap. This only happens when hardware acceleration (anti-aliasing) is enabled, however without this fontwork is blocky with jagged edges. Fontwork shadows are also distorted in slideshow mode. This happens in all Libreoffice versions.
