Movable static mesh shadow flickering in multiplayer

When i have a movable static mesh in multiplayer i get shadow flickering on the mesh itself when the mesh or the camera is moving. (In my case) best soon on a rolling sphere, 1/4 - 1/2 of the entire mesh is flickering between black (shadow) & material color at random, happens the most when it’s moving/rolling.

When engine scalability’s shadow level is at low this doesn’t happen.

This happens to me, too. Im spawning simple blueprint actors (blocks) on the map. When i walk around them, they flicker.

I made some screenshots:

The shadow in the circle shouldn’t be there and was there for a split second, like many others.

There should be a shadow from the left wall on the sphere in that circle.

The left circle: there shouldn’t be light there, only shadow
The right circle: there shouldn’t be a shadow there

Got the exact same renders on my cubes. Flickering is extremly annoying. I have it ONLY on CLIENT! How about yours? On server here everything runs smoothly.

My cubes are actualy BlueprintActors. Do you use static meshes or SM in BP?

It works in my level with a MOVABLE LIGHT SOURCE. Why?

The spheres are movable static mesh components of pawns (1 for each pawn), it happens on both my client and my server.

Hey, I have the same issue in the RollingBall map, by default the light is set to stationary and i get ugly shadow on the cubes on client and server, i set the directional light to movable and it’s doesn’t happen anymore.

That also worked for me, seems to be only required with directional lights tho, so a bug or so maybe.
