Insight
ksplash-engine-moodin has some background caching routines for simulating the transparency and the fade-in effect of the loading steps. When the session loading happens too fast, the first steps don't have enough time to finish the caching before the later steps start to happen, showing some images that look cut.
This update corrects the problem.
Affected
