The information in this article applies to:
If you apply certain custom animation effects to a drawing object that has a semi-transparent fill color, that object appears grainy or dithered as it animates during your slide show. After the initial animation, the object appears correctly.
The animation effects that result in this symptom are those that change the size of the object. These include the Zoom, Stretch, and Swivel effects.
PowerPoint displays semi-transparent objects by filling them with alternating pixels of the color of the object and the color of the background. When PowerPoint stretches or sizes the drawing object during animation, this pattern of alternating pixels is temporarily distorted.
This symptom does not appear with most of the animation effects. It is also much less noticeable if your Windows display settings are set for more than 256 colors or if you are using a faster computer.
