Strange children alpha bug when animating parent Container opacity

Hi there,
I noticed something really strange today, I was animating the opacity parameter of a parent container to show or hide its children containers.
From the viewer of this parent container, everything looks fine, but if I go one level higher, the opacity animation looks broken.
It’s a bit hard to explain so I did a TOX demonstrating it.

Are you able to reproduce this ?

I had the same results on both following systems:
Windows 11

Windows 10

Hey @michelchrome

I’m able to reproduce.

This is logged for a developer to look into it.

Thanks for the report.
