How do I remove Moire patterns from defishing?

[7C Elements]

This noise is on the side quarters of the frame, and usually is seen on blue skies and solid backgrounds. I use Mercalli and it's an artifact of the defisher function and an ActionCam.

Currently, I use 4 filtering settings together to get a pretty good removal.

in Vapoursynth:
MLDegrain, default
TemporalDegrain2: with nStep, subpixel at soft, and a 3 radius,
FluxSmooth, Spatio on,
FrFun7, default

I haven't tried Avisynth, or no xSynth.

I tried nearly every combination of settings that worked, but now the performance is very slow like 0.5 FPS, when it's usually 5.
Is there a setting that can be a stand alone filter, for this problem, and sped up?
