There was an annoying bug with that where the menu would sometimes end 
up with scroll arrows at the top or bottom because it wasn't calculating 
the size of the menu before showing it for the first time.  The code to 
lazy-load the icons was a bit of a mess, so I think I just removed it.

I think people just need to understand that some features aren't going 
to work well on lower-end hardware, and if it bothers you, you just have 
to suck it up and disable it if possible.

Patches to make the behavior better gladly accepted, of course.
