We've been looking for this issue before we post it, but unfortunately, we haven't found any discussion about it.

Apparently, this is an issue with any slider when the min-value is not positive (either zero or lesser).
Value slightly fluctuates between min-value and an epsilon-near min value.

We have tested it in a clean WPF Windows environment. The bug does not happen.
We haven't tested it with Noesis neither in Unity, Unreal, C++...

We have isolated a minimum scenario where the bug reproduces.

Steps To Reproduce:
1. Press "Decrease value" button once. (value goes from 1 to 0).
2. Press "Decrease value" button again.
Expected Result:
- Value keeps in 0.
Actual Result:
- Value goes to 3.8e-44 (almost 0).
- Whenever you press again the button twice, value toggles from 0 to 3.8e-44.

This very behaviour is not happening with "Increase value" button. It properly keeps at max value.

This is clearly a bug in the Slider logic, could you please report it in our bugtracker?

Done!

Hope it's good reported enough.

Thank you.
