Jittery noise texture on diffuse channel

I'm working on a low-poly style animation with big text and I've used noise as the texture for the diffuse channel for the text to create a papery effect. I created the text originally with MoText and made it editable, then applying displacer and polygon reducer to create the low-poly look (see the screenshot). The problem I'm having is that the noise texture keeps animating, i.e. noise is different in each frame. I'm using UVW Mapping so I get the look I want and have tried locking the UVW, using the Stick Texture tag but nothing seems to work.
Both the camera and the text is slowly animating so I assume that's the issue but is there a way to 'fix' the noise texture so that it doesn't change? Animation Speed is set to 0 in the noise settings.

your noise is not animated - try increasing the Global Scale to 10% and re-rendering, not the look you want but you can see it's not animated. It's caused by the noise being smaller than the pixels so from frame to frame as they animate (particularly slow animation) it looks like you get a change of pattern that's really not there. I think you have to increase the size of the noise to find the sweet spot where it's small enough for your look but large enough to not moiré...
