WebGL errors with 4.26.4

VictorBerchet — Wed, 01 Mar 2023 19:42:45 GMT

I have updated my app from 4.25 to 4.26.4 and got a WebGL error

184WebGL: INVALID_OPERATION: useProgram: program not valid 72WebGL: INVALID_OPERATION: getUniformLocation: program not linked @arcgis_core_views_SceneView.js?v=d508d2c9:25775 WebGL: too many errors, no more errors will be reported to the console for this context.

I was able to narrow down the issues to this code

The error is gone when those 2 lines are commented out.

Is this a bug in 4.26?

The layer is created as

this.gndGraphicsLayer = new GraphicsLayer({ elevationInfo: { mode: 'on-the-ground' } });

When I remove the elevationInfo it starts working again. It seems like a bug the API.

For some reason I can not reproduce on CodePen

I figured out the root cause. I had:

// https://community.esri.com/t5/arcgis-api-for-javascript-questions/3d-scene-view-slow-with-es-modules-from-4-21/m-p/1218085 externalRenderers.forceWebGLContext(1);

In my code. Removing that fixed the issues.

What about adding an error log in 4.26? (or ignoring the call).
