As far as I can tell the startup splashscreen after logging in on Kubuntu with Plasma5 seems to be a pointless busy loop that locks up the user interface for several seconds while nothing is achieved and everyone would be better off disabling it.

Is this the case? Or am I missing something?

What could the possible justification for such a pointless delay be?

Background: I was trying to tweak my startup/login backgrounds on my Kubuntu install from the hideous default image and ended up finding this thread.

Running the command

kcmshell5 splashscreen

Allows you to select "None" as the splash screen theme.

Since doing so my desktop starts almost instantly without the silly progress bar and painfully slow to fade out splash screen. Seriously, I really like the new look KDE desktop it's great work, but this fake delay just seems mad, someone should read this.
