Here's a link to a video I've just recorded about the issue:

This downward motion of the camera every time I enter stealth is okay for a character that doesn't ignore the movement penalty of sneak and will stay crouched when moving, but as you can see, as soon as I press the W key my character stands up to run and you can see that that stealth reticle is almost parallel with my waist, but when I exit stealth, then the reticle is back to being parallel with my shoulders.
This is without N'tak Camera. I have altered almost every setting that could be altered and even reset the addon to deafault settings mutiple times, nothing I change will make this camera stay in the same place for both steath and normal running.
I hope this video helps
Edit: Also disabled every single addon, exited the game completely and tried again, but this did not solve anything
