When we upgraded from 100.7 to 100.8, we immediately noticed a degradation in visual quality.
See the two examples below. Notice the edges of the black hexagon.
We see this on multiple symbols/types.
I've attached a minimal mmpk, in case that helps.
Is there anything we can do about this, or will this be fixed soon?
The visual difference is caused by a change in v100.8 where we now use the Dynamic RenderingMode for Feature Layers with point geometry when the Map has a ReferenceScale set. Thanks for reporting the issue above - we're investigating and hope to be able to resolve this case in an upcoming release.
To restore the original behavior you can set FeatureLayers to use the **Static** RenderingMode either by setting the FeatureLayer.RenderingMode Property on a per-layer basis or by setting the Map.LoadSettings Property / LoadSettings.PreferredPointFeatureRenderingMode Property. In both cases the property should be set to FeatureRenderingMode Enumeration value Static.
This workaround fixed the problem for now.
A few notes:
Apologies for the misdirection, I replied while in the midst of an in-depth discussion about Dynamic and Static. I've updated my comment above (Static being the all important mode in this case).
