IdentifyLayerAsync on two layers flickering in 100.7

Question

I have made the update from version 100.6 to 100.7.

In our WPF app we have more than one layer because the user groups have different. In the GeoViewTapped Event of the MapView we have a foreach-loop of the OperationalLayers. If the layer is a FeatureLayer we call the function IdentifyLayerAsync for this layer, the position and returnPopupsOnly = false.

With the SDK 100.7 the layers seem the flicker with every call of the method. Maybe  the layers have to redraw with the call.

I was searching the release notes but I cannot find an entry for this part.

Hello, I also have the same problem with flickering. I have a custom layer that I use for my own labels that only contains text graphics. In 100.7 when I call IdentifyLayerAsync on a completely different layer the text graphics flicker (none of my other graphics flicker). In 100.6 everything works fine.

Sandra, Thanks for providing the video. That really helped. The difference was that my layers did not have labels enabled.I can reproduce the problem when I enabled the labels.

Note, it is not the layers that are flickering, it is just the text/labels that flickers.

I am not certain about the workflow of your app but the only workaround to avoid flicker is to disable the labels for layers.

I have logged this a bug in our internal bug management system. Thanks for reporting this regression.

Let me know if you have any questions.
