While the KDE Plasma 5.8 LTS Beta splash screen (after login but before desktop appears) is has a very slick spinner animation it should hide or disappear or change to full circle (maybe) instead of pausing in place while fading out into the desktop. Reproducible: Always Steps to Reproduce: 1. Login to your KDE Plasma 5.8 LTS Beta desktop. 2. Watch the splash screen animation. Actual Results: The pretty looking spinner smooth animation pauses midway while the splash screen fades out and the desktop fades in. Expected Results: Spinner animation should probably hide or disappear or maybe show some full circle or check tick mark to indicate it's completed.

It's actually supposed to do just that and if I run "ksplashqml --test" it works. The problem is that the splash (at least the current infrastructure) doesn't have a "about to quit" signal, it basically has 6 (or 7?) stages which are increased by various services starting (you know previously we had this progress bar). At stage 2 it animates the spinner in and at stage 5 it is animated out again. However, it can happen that the subsequent stages happen in such quick succession that the spinner is still visible and once the window closes only its texture is kept and faded out resulting in a frozen spinner.
Indeed, which means this needs to be fixed in the engine I think.
