Sounds like Emacs is looking for a suitable font to display these symbols. That's normal, and happens only once in a session for each symbol. I see this on my systems, although the "accumulation" doesn't happen here: the short delay is independent of the number of identical symbols on the screenful Emacs is about to display. > This bug happens both on master and 25.1, with official binaries. This > does not happen in 24.5. Emacs 25.1 changed the font used for these symbols, but otherwise I see the same delay in Emacs 24.5. Bottom line, I don't think it's a bug.
