Custom scene depth issues in UE 5.2 (worked fine in UE 4.27.2) ?

I have a custom decal material (I don’t recall where I got it from, probably from Twitter X ) that worked wonderfully in both SM5, ES3 and mobile Vulkan in UE 4.27.2. When I ported project to UE5.0, the material broke.
I re-ported the project to UE5.2 last night and material is still broken. Can someone please point out what’s going on there?
How it looks:

The decal should looks like a nice solid splatter (like blood splatter), projected onto surfaces behind it. Right now it flickers and has that nasty dither across the entire surface of decal.

Thanks beforehand

Apparently ditherAA doesn’t work well on Q2, so just removing the node did the trick. However, there is still issue with decals on skeletal meshes (nor rendering properly in stereo).
