Shouldn't be an issue in kepubs.

Here's an example of three consecutive pages. Pages 1 and 3 have 20 lines of text, but page 2 has only 19 lines. Perhaps the problem is that if there is more than one new paragraph on the same page, it takes up enough extra space that line 20 won't fit. The last line on page 1 is 12 pixels closer to the edge than on page 3, which is all one paragraph.

Ah yes, the spaces between paragraphs are the reason here. I remove those from my books.

What CSS nonsense is the cause of this particular behaviour?

Usually a non-zero margin-top (and/or margin-bottom) on this particular book's main body paragraph style.

I know exactly what the reason for page 2 having one less line. It's because you have paragraph spaces. page 1 has 1 paragraph space. Page 3 has no paragraph space. Page 2 has 2 paragraph spaces so there's not enough space for another line. The solution is to remove the paragraph spaces and all three pages will have the same number of lines.

I get rid of paragraph spaces. Here is the code I use for <p>. I also get rid of <p class="someclassIdonotneed"> for the majority of paragraph styles. But if you do have something such as <p class="tx"> here is c.tx that doesn't have paragraph space.

p {
  margin-top: 0;
  margin-bottom: 0;
  text-indent: 1.2em;
.tx {
  margin-top: 0;
  margin-bottom: 0;
  text-indent: 1.2em;
}

Yeah, in my experience, 8 out of 10 sideloaded books have these ugly spaces. For years now I have been using this code when converting to kepub with Kepubify! An absolute must.

Dumping paragraph spaces is important to comfortable reading.

Is this something that you can override in KOReader? If I could configure such settings to automatically apply to all of my books, instead of having to manually edit them one by one, it might be enough for me to switch over from Nickel.

No idea. I edit the CSS. It's very easy to dump paragraph spaces.
