I found out how to replicate it, and I found out something bad which is also a bug in current compile.
Trying a number of combinations, here's what dropped out:
- with single spacing of the Scriv document, I didn't see the font splitting, on a couple of files
- but after tryiing a number of combinations, I did replicate
- If, like both reports, you set _double_ (2.0) line spacing on the document, bingo: the splitting occurs
- I tested and found the splitting on both Compile to PDF and Compile to Print -> normal Microsoft PDF printer
- This last test turned up another big problem with Compile in its present state.
- The extra problem is a serious interaction with Font Hinting setting, as for our improved screens
- on Compile to Print -> Microsoft PDF printer, this problem is not observed
- But on Compile to PDF, with Font Hinting unchecked and Scrivener necessarily restarted, big distortion
- The font in the PDF is distorted to become larger than it should be,, perhaps mainly in height
- It's also become far too heavy, like a mis-calibrated Bold
- The font has lost its proper kerning, so that letters are too close together and overlap
- If you return Font Hinting to checked and restart Scrivener, then these PDF distortions don't occur
So I would say that two problems should be Listed. That would be the original font-splitting issue, now that we know how to repeat it, and this new issue with Font Hinting and Compile to PDF.
Given the improvement in screen clarity with Font Hinting unset, plus this Compile to PDF issue when it is set, I'd like to suggest that defaulting it to be unset for editors, but forcing it behind the scenes to be set duriing Compile to PDF action would be a quite reasonable solution to speed getting through this period and getting out the release.
Persons who preferred the spindlier screen appearance with Font Hinting set could simply check the box in their own options, for now. All the deeper issues could be postponed for a relaxed post-release exploration -- or Qt fix , etc..
Best I would think of, anyway...
