(setq inhibit-compacting-font-caches t) seems to help. I did not try Symbola.

If I use (prefer-coding-system 'utf-8), I do not get the slowness
anymore, even if inhibit-compacting-font-caches is nil, and even after
propertizing the text. However, the font changes from PragmataPro Mono
to Malgun Gothic, which seems odd too.
if I use both (set-locale-environment "English") and
(prefer-coding-system 'utf-8), the issue returns.
