SUMMARY
Sometimes the magic lamp's animation gets played out incorrectly. Half of the minimizing animation is repeated, which at normal speed makes the effect look glitchy. This isn't a general bug because I've only encountered it on this device and the bug doesn't appear when testing with a new user. 

STEPS TO REPRODUCE
1. (trigger something (?) userspace related that's interfering with the animation)
2. observe the animation get played out wrongly

OBSERVED RESULT

EXPECTED RESULT
Effect works as intended.

SOFTWARE/OS VERSIONS
OS: Manjaro
KDE Plasma Version: 5.14.3
KDE Frameworks Version: 5.52
Qt Version: 5.11.2

ADDITIONAL INFORMATION
Qdbus output is attached.

Magic Lamp and Scale Minimize effects are not fwends. Disable either Magic lamp or Scale Minimize effect (see installation instruction https://store.kde.org/p/1267839/)

Ah, that's the root cause. I forgot I had it turned on.

Thanks!
