Dereference texture error logged when text symbol is removed from graphics layer

TonySchwebach — Wed, 05 Jun 2024 21:18:32 GMT

I have a 3d SceneView with a graphics layer and a point graphic with icon and text symbol layers. When the graphic is removed from the graphics layer, the console logs this error message:
"4.29/:132 [esri.views.3d.webgl-engine.lib.TextureRepository.RefCountedTextureImpl] Cannot dereference texture that has no references!"

The error only seems to happen when the TextSymbol3DLayer() is included in the symbol layers. If it is commented out, there is no error message.

How can I avoid or suppress this error message?

I created the html page below which replicates the error when the "add/remove" button is clicked.

We have the same problem in our application. I tried a lot of things, but I didn't come to a solution. But I do know that this bug already came up with 4.28. Maybe this helps the developers of esri.

Hi Tony,

Thanks for reaching out on this topic and the good repro case. This error shouldn't occour anymore in the upcoming release.

@ThomasKnabl @ We are using 4.30.9 version and still appearing this error in 3D mode using the following code. Should it be already solved? Thank

graphicsLayer.removeAll();
