i wonder if it has to do with the icon itself - maybe its svg and the loading
an rendering by librvsg is.. of course.. slow (it may be a complex svg). but
why is it being re-loaded. not sure there. it should really only be loaded once
- but you'd be able to find out what the lag might be with some strace -tt
(adding in timnestamps). i am wondering if its reloading at all - or if its
some icon search path trying to find the icon and goign through an exhaustive
search then failing. don't know - but more info will help.

one way to "rule out" rsvg is to check if u have an svg loader for evas - if
you have an svg loader module - just rename the module.so file in the dir to
maybe disabled.so (then evas wont find it) and see if it persists.
