How does shrunk text in beamer override the foot line?

edit

When text in a beamer slide is shrunk, it may overlap with the foot line if the original size of the text was larger than the available space on the slide. This can happen if the foot line contains longer text or if the layout of the slide is complex.

In such cases, the shrunk text takes priority over the foot line, as it is considered more important for the content of the slide. Beamer does not automatically adjust the foot line to accommodate the shrunk text.

To prevent this issue, one can manually adjust the size of the foot line or the layout of the slide to ensure that the shrunk text does not overlap with it. Alternatively, one can use the \vspace command to add some extra space between the text and the foot line.
