Empty page between chapters while reading EPUB
When I open Viewer to full screen, I have text in two columns.

If end of chapter fits into one column - the second column is empty and next page is a start of next chapter.

But if end of a chapter takes both columns, then I have an empty page before starting the next chapter.

Going backwards - open a chapter from TOC, scroll up - again an empty page. And then the whole screen is filled with text, even if going forward the previous chapter had text for only one column.

Is this a setting somewhere or a bug?

Its an inevitable consequence of how pagination works with the underlying HTML rendering engine.

Maybe it is possible to adjust that "underlying HTML rendering engine"? Or use a different renderer? The empty page issue does not appear in the Viewer with other formats - maybe it would be possible to do a silent conversion from HTML to whatever is used in other cases?

I am not sure how forced HTML renderer is in the case of EPUB - but is it possible to update that renderer?

Or maybe do a silent conversion to another formats so instead of faulty renderer the better one can be used?

The HTML rendered is chromium and HTML is used in all cases, indeed all formats including EPUB are converted internally to HTML which is rendered.

You keep using the word FAULTY.
It WOULD be faulty if it did NOT work that way for an uneven page count when in 2-up.

Print books (mainly Hardback) always wanted The first page of a section to be on the right. Sometimes, the Left would not have any content, thus BLANK.
If you dont want blank pages. don't view 2-up

Especially PDF.

If you are using 2-up viewing with PDF and the first page isn't on the right (for left to right languages), then the PDF viewer is wrong.

It is "faulty" because the viewer is able to show other formats without a blank page.

But in the case of EPUB - the first page of section is always on the left. And if previous section ended on the right - we have a complete blank page between chapters.

So the only way right now to read EPUB is to convert it into FB2/MOBI and read that format.

The problem is only with EPUB.


And no, I do not choose the 2-column view, it is an automatic if the Viewer is wide enough. And I cannot find a flag in preferences to disable it. That is another annoying issue with the Viewer, but it can be overlooked for now.

It has nothing to do with formats, as I already explained to you. And you can specify exacly how many columns to use in the viewer prefernces under page layout
