Libre Office 3.5.1 on Windows Vista 32 bits SP2:
When the Hardware Acceleration for Image rendering is "on" in the Tools->Options menu, the slide show is ugly with text distorsion and the background image may desappear.
To reproduce this bug with hardware acceleration "on":
1. start Impress with the Assistant
2. select the "From a model" option
3. select the first one of the two models that are proposed by default
The first proposed model is "Présentation d'un nouveau produit" in the fench version and should be "New product presentation" in the english version.
4. launch the slide show: the background image desappears and the distorted text remains the text of the first slide!
If you select the second one of the proposed models ("Proposition de stratégie" in french, should be "Strategy proposal" in english), the background image remains but the text is distorted.
Setting the hardware acceleration "off" gives clean slideshow.
