Emacs has support frame background transparency since 29, add `:mask
heuristic` to overlay property list to make its transparent part masked
when displayed in a transparent frame.
There is a related thread
[[https://emacs-china.org/t/org-latex-preview-png/29167/12]] .
This is my first time to try to contribute, if I have anything done
wrong, please tell me!
