Video showing the disturbing flash

SUMMARY
With new Plasma 6, when the start animation finishes and the desktop is shown, it flashes white during a small fraction of a second (yet the plasma widgets are drawn as expected, it's just the background it seems).

Pause the next video at 00:03s to see the effect.


STEPS TO REPRODUCE
1. I've selected a startup screen derived from Nordic-blueish. I don't think it's related to this, since the white flash happens after the animation is done and the desktop is already displayed when it happens
2. Login with a dark theme (and ideally, a dark background so it's obvious). 
3. 

OBSERVED RESULT
Got a disturbing flashing white screen upon login.

EXPECTED RESULT
No flashing white screen

Sorry we were not able to get to this bug report yet! I can't reproduce it myself. Can I ask you if the issue is still happening in Plasma 6.3.4 or newer? Thanks a lot!
