Hi @Tsub4sa80. This is an internal exception that we swallow internally. I'd treat it as an internal implementation detail that you can ignore. I am curious... Are you seeing this in the Visual Studio output window, or somewhere else?

@Tsub4sa80 would you be able to share the WMS service you're using along with some steps so we can try this out? A short recording/video of the problem happening would help us understand the nature of the problem better as well if that's a possibility.
The latest version of our samples viewer app for Windows is here if you want to download and try it out: https://www.arcgis.com/home/item.html?id=c78d9ccabc5a4dcf9b74c11f55c7a279 . It would be helpful to know if the problem you're seeing happens with the sample itself using our example service.
@JamesBallard1 thanks you for your prompt reply. we have also introduced toolkit OverviewMap in our software. I found out that by removing it, the pan / zoom issue does not occur. I suppose that requests are sent simultaneously to the WMS server, thus creating rendering problems. I don't have much time, so for the moment the overlaymap functionality will be disabled, to avoid reducing system performance.
