Summary
I find that in some cases locations of labels seem to be displaced, as if some indexing is off by one. Until now, I have seen this only happening with labels bellow a line, but not above. Not with text_repel, but maybe just a question of available space.
Minimal code example
I will add a minimum example later today, but as you may be getting ready to submit the new version, this is shown as a warning of a proper example I will add by the end of the day.
This example demonstrates the issue, although it is not a minimum one.

Suggestions
I have no proposal at the moment. This seems to be a bug.
