Rawtherapee: Issue with noise reduction in editor

[heckflosse]

Steps to reproduce:

Open a noisy image in editor and apply 'Default ISO Medium' profile.
Zoom to 100 %. Most of chroma noise is removed, good!
Now go to exposure tab and press reset button, most of chroma noise is removed, good!
Now press auto levels button, chroma noise is visible again, bad!
Now zoom out to 50% and again zoom in to 100%, chroma noise is removed.

There's something wrong in editor...

In my case, good till reset button.
But same issue occurs after applying auto level again.
And noise disappears by dragging image with mouse left click on image even without re-zooming.

I updated my post because you're right that it's good until pressing auto level button.
As it's also good not only by re-zooming but also by dragging it's not a critical issue but still one we should solve.
