Hey guys here you have a list of already known and confirmed issues with renderers in Kobo:

EPUBs - Adobe RMSDK in Kobo flavour. (I don't know if they are present or not in other new readers from other brands):
- Widows and orphans are somehow buggy. Sometimes you get some extra blank space at the bottom of the page where one or two lines from the trailing ones in the next page could have been perfectly moved to that space. (But already said: the long paragraph bug is gone).
- font-variant: small-caps doesn't still work.
- white-space: nowrap doesn't work at least applied to <span> tags. I use it a lot in dialogues in Spanish books (link to Calibre Editor thread). And I can assure you that it perfectly worked (works) in my old Sony PRS-650.
KEPUBs - ACCESS:
- Widows and orphans DO NOT WORK at all. It doesn't matter what you set, you always get a 1 (off) behaviour.
- @page, page-break-before/after CCS settings do not work.
- The aforementioned problem with trimmed letters in the right margin when that margin (both in book and GUI) is set to 0 and the text is justified. Italic ending fs are the perfect candidates for this issue.
- The renderer adds extra space around certain punctuation marks when the text is justified. I mean the punctuation marks are "separated" from their partner words. Examples IIRC:
  - (I'm fully sure of this one) Long/Medium dashes:
    Code:
```
This—code
```
    is justified as
    Code:
```
This—  code
```
    (Awful in Spanish dialogues).
  - Ellipsis or quotes which also get separated from following punctuation marks as in
    Code:
```
(“Bla,   bla”  )
```
- Books with embedded fonts tend to get white/blank screen when changing "chapters" (I mean when a new html file is loaded). I mean that sometimes when you turn page and the new chapter should be rendered, you just get a blank screen. You have to tap/swipe one, two or three extra times till the new chapter is correctly rendered. But it doesn't ALWAYS happen. Sideloaded kepubs and embedded fonts don't work fine together...

(And possibly some other ones I don't remember right now...

)
