What is VLC's 'building font cache' doing everytime I update the version? It takes forever on my otherwise reasonably fast system. What is it doing?

VLC is searching your system for the fonts it needs to use for subtitles and on screen messages. It takes time because it is searching your entire system, and copying the fonts it finds to its own directory, as I understand it.

You can disable it as follows:

Rebuilding the font cache not only takes time, sometimes it can make VLC hang completely, which can get old quickly. To make it stop, just open up VLC and go to Tools > Preferences. Hit the “All” radio button in the bottom left hand corner, then go to Video > Subtitles/OSD in the left-hand pane. In the Text Rendering Module dropdown, pick “Dummy Font Renderer Function” and hit save. The next time you open VLC, you should be free of that annoying cache-building dialog. Lifehacker
