It sounds rather plausible. AFAIR, org-table basically deletes and redraws
the table (but I didn’t check the code), which would modify the buffer.
Perhaps org-table-align could run in a temporary buffer and only inserted
the "new" table if it the result differs from what’s already in the
buffer.

Andreas, do you want to try to fix this issue?

Thanks,
Rasmus
