I have been using display-line-numbers in emacs 26+ for a while now,
with org-indent-mode, and have not seen any strange behaviour along the
lines described by the OP.  There are some issues with the width of the
space for line numbers that arise when hundreds or thousands of lines
are hidden but this is not due to org.
