I have some slide decks in Impress I’ve been using for years that suddenly are having graphics errors during presentations on slides with a mix of animations and shadows. For example, when presenting the only slide in this example presentation, the objects with shadows have the shadowed text redrawn after each animation step:
To mitigate this, I’ve had to manually break the slide apart into multiple smaller animation steps, which is less than ideal if I need to edit any individual frame.
