For anyone else no more hoping in a fix from Unity, this workaround actually worked for me:

Still bugged in 2019.4.21f1.

Almost every week you think Unity reached rock-bottom...

Still broken. No plan to fix this?

Problem is still present in 2019.4.19f LTS. Why it is considered fixed?

It still happens in version 2019.4.13 it's really a big problem, is there a chance that it will be fixed one day?

Issue still present in 2020.1 version. Analysis: the Cloth vertex deformation code seems to constantly recalculate the SkinnedMeshRenderer bounds and it messes it up.

Fix: add this script to your SkinnedMeshRenderer object or higher in hierarchy.

using UnityEngine;

public class FixClothBounds : MonoBehaviour {

private SkinnedMeshRenderer[] Renderers;

void Awake() {
this.Renderers = this.gameObject.GetComponentsInChildren<SkinnedMeshRenderer>();
}

void OnRenderObject () {
foreach (SkinnedMeshRenderer smr in this.Renderers) {
smr.localBounds = new Bounds(Vector3.zero, new Vector3(10f, 0.2f, 10f)); // Paste your meshes real bounds here
}
}

}

Issue still occurs in 2019.4.0 and 2019.4.3. Is there plan to integrate fix to next LTS release?

Hi, thanks a lot for sharing this with me. I am starting a new startup and was reading a business plan on www.ogscapital.com/service/business-continuity-plan/ website and really liked it a lot. I will use this plan to make my startup successful.

Still bugged for me in 2019.4.0 ... >_<

It works a bit better if my root gameobject (not the root for the bones) scale is (1, 1, 1), but in that case some normals get messed up and the skinnedmesh still disappears when it shouldn't, although less obviously.
