Quoting bulia byak <buliabyak@...400...>:

it renders and caches [the icons] the first time you open the dialog, which is better IMHO. After that it opens much faster.

I don't know... it seems like we've traded "slow to start up" for a perception of "slow everywhere".

I find it's more frustrating to be able to get partway into the app, only to have to repeatedly wait as additional icons get rendered, than it is to have a single (albeit longer) wait at the beginning.

It might be better to render the icons as an ultra-low-priority idle task (not a thread, since we're not thread-safe).
