Based on the description of the slide, the following problems can be identified:
- The slide contains too much text.
- The slide does not have an image or visual aid.
- The slide does not have enough empty space.
The text size is not mentioned explicitly, so it cannot be determined if it's too small. Additionally, the description does not suggest any issues with the readability of the text based on the background color. Thus, those two items cannot be checked off as problems.
