I don't know. Was your Emacs built with HarfBuzz? You didn't attach
the data collected by "M-x report-emacs-bug", so I cannot know.
I suggest to start by attaching a sample file that exhibits the
problem, as text, not as an image, and then showing what it looked
like in previous versions of Emacs and what it looks like in Emacs
27.0.91 on your system. Also, please tell which font was in use when
the problematic display was produced. Then we can look into this
issue and see what could have caused it.
Thanks.
