This looks related to the failing rendering of road labels

I found this issue that may be interesting, it highlights the same errors. Somebody points to:

https://github.com/gravitystorm/openstreetmap-carto/blob/master/CONTRIBUTING.md#map-icon-guidelines

I am not 100% clear what is the SVG that causes the issue, but maybe it is not compatible with the new mapnik? If so cleaning up may become a real fun..

Unfortunately even clearing the errors the rendered labels are still broken.

Update: If I force a specific sans font things are rendered better. I think that the errors are just a red herring (just ignored before) and the root cause is the order we load the fonts.
