I was able to use git bisect (on master) to narrow down where the problem
started (for me, at least):
27466a38bcd6f5f3c6bd3c61b8ec9253d4dbf4e4 is the first bad commit

Fix `org-string-width'
* lisp/org.el (org-string-width): Better handle various invisible

I'm not sure what's going on ... is anyone else seeing this problem with tables?
