Features flickering in 3D view when FeatureFilter present

Hello, I have an issue with features 'flickering' in and out whilst moving the camera around in a 3D scene, when the layers have a FeatureFilter applied. The setup uses arcgis/core version 4.28.10, with a FeatureFilter being applied to OGCFeatureLayers and FeatureLayers in a WebScene.

Here's a clip of the issue;

I tried creating a mirror of the project setup with some test data in a codePen, and wasn't able to reproduce the same behaviour (maybe having more data in the layer makes the problem worse?). A similar flickering effect can happen when features overlap in 3D space (z-fighting), and when viewed from a particular angle (above or below), whether or not they have a filter on.

To test my theories I've tried the following in my project with no luck;

Included only one feature layer in the scene,
Turned off the renderers and various other view/layer config options
Using different Layer types (GeoJSON, OGCFeature)
Turning off base layers and ground layers

Any help on this would be much appreciated!

Thank you,

Chris

Hmm, really hard to say what causes this without an actual reproduction case.

Could you still share the codepen (even if it doesn't reproduce the problem), so we have a starter what to look?
(We specifically need to know what data and renderer / symbology is used, and how featureFilter is applied)

Also, can you check the following:

Can you check if it also happens with 4.29?
Can you confirm the flicker does not happen when FeatureFilter is not applied?

As said, hard to say but from the current recording I would say:

it's not z-fighting (happens only with coplanar faces)
FeatureLayer, GeoJSON, OGCFeature should not make a difference (the internal rendering is the same on those)
