Strange granular fades

[William Androids]

Can anyone help me? I'm getting this kind of granular opacity fade in adobe after effects. it' s only on some text layers - not on others. Can't figure it out, It's in the render too.  I've been through all the layer values. Stumped. Not usingany effects, just animating fill.

Ok but we need much more information to try to help you. Tell us how are you making it, all possible useful details please. Animators? Adjust Layers? If you can please upload a screenshot after select layer en press U key twice to see modified options.

Start by checking your layer blending modes and layer styles. Also check your graphics card and hardware acceleration settings. inadequate graphics hardware can easily cause al lsorts of weird artifacts.
