film that shows the problem

SUMMARY
When I start two Applications at the same time and they "jump" at the same time, there is a graphical problem, just see the film below.

STEPS TO REPRODUCE
1. start two applications almost at the same time
2. wait a moment

OBSERVED RESULT
The icons of the applications are briefly on top of each other.

EXPECTED RESULT
The icons stay where they should be.

I dont think this is fixable... it is the way plasma libtaskmanager works to remove and add tasks in different state.

Nonetheless let's leave it open for the future and as reference.

in my latte git version system this is reproducable on when the launchers are at positions 0 and 1, for any subsequent positions I can not reproduce.

(Yes, it's only if the applications are on first/second position. I forgot to write it in my first comment.)
It's okay if it's not fixable, so it's not very problematic, but it's a little bit wired.
