It seems to be caused by the CSS supplied by Pandoc. 

I found this SO Thread about it but none of the suggested solutions worked for me.

Here's one single small HTML page taken from the Pandoc generated EPUB file that has the relevant `sourceCode` CSS.

Thanks for helping!

Gabriel.

Do you think it is caused by some CSS which is supplied by Pandoc or do you add any CSS of your own? If the latter would you mind sending the CSS so we can have a look at it? (Off list is OK but be warned that my CSS knowledge is a bit stale. It is probably nothing complicated though.)

It is definitely CSS related but I'm just really dumb when it comes to manipulate CSS, would appreciate any help.

I have converted the Pandoc generated EPUB to EPUB once again using Calibre and it renders properly. When I resize the screen there's no scrollbar.

It might be. I'm not really sure, to be honest.

Isn't that an issue with the way your epub reader displays things rather than with Pandoc?

Hi, is there any way to avoid having horizontal scrollbars in code highlightings? I would prefer the text to be rendered in different lines instead like MOBI does it.

I couldn't find anything related information in Pandoc's manual. While searching on Google, I stumbled upon this blog post which advices to convert first to HTML and then use Calibre to convert to EPUB but I've tried it and I didn't like it.

Thanks,

Gabriel.
