Setting this to t doesn't make any visible difference to bug 21028. Was = it introduced to solve a different problem? IOW, when I run (building on the example in the 21028 thread) src/emacs -Q -mm --eval '(setq inhibit-compacting-font-caches t)' -l = 21028.el 21028 -f prettify-symbols-mode I get the same speed issues (each redisplay takes > 5 seconds), regardles= s of the value of inhibit-compacting-font-caches.
