No it's because it's a well known quirk of the kepub renderer. If you want to stick with kepubs you need to increase the line spacing a bit.

Another option is to change to reading standard epubs instead. The Adobe renderer used for epubs doesn't have this problem.

Hi Jackie.

Thanks for the reply.

I don't want to forgo the advantages of Kepub, so I'll see if increasing the line spacing by one step does the trick. I have the "My 24 line spacing values" patch enabled.

[rashkae]

Yup, that would be what's causing your problem,, the custom line spaceing values allow reducing line space to less than what Kepub reader can support. (about 1.2, or 120% line height)

[droopy]

rashkae,

I'm not following. 1.2 or 120% isn't "reducing line space". It's increasing it. 120% is bigger than 100%.

[NiLuJe]

Which is the point. If you go below a certain threshold, ascenders risk getting chopped off at the top, and descenders risk getting chopped off at the bottom.

As the actual effective line-height depends on font metrics, we don't have a magic value for you. Just play with font sizes & line-height until you've found something that works for you. And, yeah, that'll involve *increasing* line-height.

@rashkae was taking about the *stock* behavior as an example of why you're running into trouble with custom values (1.2em is a common standard for line-height, and it can even look decent for font with tight metrics).

[Quoth]

Really 120% is sort of 100% because it's a sensible minimum for most fonts.
