While working in Scrivener for Windows (version 220.127.116.11) with several large documents in the Draft folder of the binder, using Scrivenings mode causes some bottom portion of the larger text documents to NOT display (i.e., the text is replaced by white space, meaning blank canvass space). Going back to the regular, non-composite (i.e., non-Scrivenings mode), again shows the entirety of the large documents individually.
This is a very serious bug, and makes using Scrivener with large documents highly problematic for me.
ALSO, when a given document has a VERY different ruler (e.g., not so wide and different tabs) than documents above and below it within Scrivenings mode, that ENTIRE document does NOT display (i.e., it just shows as all white space on the canvass), but the documents above and below it do display. This too is a serious bug in Scrivenings mode. I mention this latter bug here because it may be related to the one above, since in both cases, the text that should be displaying in Scrvenings mode instead shows as all white space (just a white canvass with no text).
