Hello,
We’ve been using a regular LayerOverlay to hold our InMemoryFeatureLayer, but recently it started leaking a massive amount of handles.
We looked into the forums and found that the handle fix should have been improved with 14.3.2, but we are still on 14.3.1.
Instead, we updated the LayerOverlay to a FeatureLayerWpfDrawingOverlay, which resolved our handle issue.
The only negative effect we see from this now is that our HaloPen is not visible at all.
Our text style is still being applied, we can change the color, font, etc, but setting the HaloPen does nothing anymore.
When we revert to the LayerOverlay, the HaloPen works again, no other code changes.
Is there some additional properties that need to be set to make this work, or is this a known issue?
