Comment (by eriktorbjorn):

 The slowdown was introduced when we started decoding frames on demand,
 rather than in advance, to fix a crash at the lab table. See
 https://github.com/scummvm/scummvm/commit/046e39428bae509f087bc0ffc25b1f925f565435

 If I understand correctly, the intro animation does ''lots'' of reads from
 the same resource file, and for each of them it has to decompress the
 ''entire'' resource file. So while each image is decoded in a few
 milliseconds, that adds up to a lot.
