@micelic Thank you for sharing your sandcastle demo with the community. It looks like sections of the KML are being hidden as I zoom towards the terrain. ![image](https://global.discourse-cdn.com/cesium/original/2X/0/0b3da11338cc6683325d6ba8629f7e9331556db0.jpeg) This error might be related to multi-frustum artifacts. Thus, it may be fixed by enabling log depth. Please try setting ```auto scene.logarithmicDepthBuffer = true; scene.camera.frustum.near = 0.1; scene.camera.frustum.far = 10000000000.0; ``` -Sam ---

Hi Sam. I see the same issue. This is what I did on your sandcastle. var viewer = new Cesium.Viewer(“cesiumContainer”,{terrainProvider : Cesium.createWorldTerrain()}); viewer.scene.logarithmicDepthBuffer = true; viewer.scene.camera.frustum.near = 0.1; viewer.scene.camera.frustum.far = 10000000000.0; Let me know if this is what you were asking. Thanks, Carlo ---

Hi Sam Here is another sandcastle example ![image](https://global.discourse-cdn.com/cesium/original/2X/2/23e947582a45b0c7c036f080993629729762ec12.jpeg) ---

@micelic Are you still seeing the same issue even when you update your project to include the following code? ```auto scene.logarithmicDepthBuffer = true; scene.camera.frustum.near = 0.1; scene.camera.frustum.far = 10000000000.0; ``` -Sam ---

I have some code with the same bug. Adding those 3 lines didn’t fix it. If I find a solution I’ll post it here. It vanishes if I zoom in and generally looks strange as I pan and tilt the view. The same code works perfectly with other data in a different location! > const redLine = viewer.entities.add({ > name: “Route”, polyline: { > positions: Cesium.Cartesian3.fromDegreesArray(posns), > width: 15, > material: Cesium.Color.RED, > clampToGround: true, }, > }); > > ![Image1](https://global.discourse-cdn.com/cesium/original/2X/6/6d5b95824d1fc73dae045157e3548c56b04c418a.jpeg) ---

Hi everyone, Has there been a solution to this issue? I am also facing a similar challenge with icons and even labels. When zooming in, they dissapear. ![Screenshot 2023-08-16 at 21.59.16](https://global.discourse-cdn.com/cesium/original/2X/f/f5ac872052632986feb15d95a88cb0d13539b667.jpeg) ---

Hi @elolelo, I would recommend setting the [`disableDepthTestDistance`](https://cesium.com/learn/cesiumjs/ref-doc/BillboardGraphics.html#disableDepthTestDistance) property for billboards and labels in this case. ---
