I was playing around formatting an epub today, and formally discovered what may be a bug in the line spacing adjustments in the font adjustments on the reading screen.

I've been seeing this behaviour for a long, long time, just never got to the point were I could test it. I think it is happening on both the Glo and the Touch (and probably the Mini).

The css element line-height controls the line spacing.

It looks like the smallest line spacing that Kobo allows you to set on the font adjustment screen is about 125%. It will gladly increase the line spacing above this value.

A line-height of 100% is a more natural setting.

In any case, the line spacing slider should have 100% in the middle, allowing you to have larger or smaller line spacing than 'normal'.

If the line-height is set in an epub's css, then the line spacing adjustment is disregarded. This is why setting line-height in the file's css is not a real solution.

The above was determined using Amasis on a Glo with a side-loaded book.
