StreamLayer 4.29 | Features have black blinking square

[orahlagi]

Hey, I just upgraded from 4.28.10 to 4.29 and noticed the features are blinking non stop, it's only stop on a very high zoom level.

I'm using sendMessageToClient method on StreamLayer.

I'm not sure how I can give an example to reproduce it, I didn't change anything in my code, I establish a layer with the following config:

new StreamLayer({
idField: 'some-id-field',
fields: some fields as FieldProperties[],
timeInfo: { trackIdField: 'TRACKID' },
geometryType: 'point',
objectIdField: 'something'
})

Then I'm adding features as a batch:

myStreamLayer.sendMessageToClient({
 type: 'features',
features: [{attributes: {someAttributes}, geometry:{x:someCoordinate, y:someCoordinate}}]
})

Hope you can see the attached video.

Hi there 

Can you please paste the renderer code (especially the symbol part) here? Thanks

@UndralBatsukh Thank you.

Here you go (the uniquevalueinfo and the expression has some logic that I removed in the code example):

{
      visualVariables: [
            {
              type: 'rotation',
              field: 'angle',
              rotationType: 'geographic',
            },
          ]
      valueExpression:
        'someExpression...',
      uniqueValueInfos: [
        value: value,
      symbol: new PictureMarkerSymbol({
        height: someHeight,
        width: someWidth,
        url: url,
      }),
      ],
    }
