Bing Maps WPF Control: map tiles get scrambled, why?

I've got the Bing maps WPF control included into my Windows Forms app (via ElementHost) and when viewing the map (also in Design Preview), the map tiles are scrambled. I'm behind a company firewall and accessing the Internet without firewall is not an option.
What is the cause for the scrambled tiles?

The problem is that my application is really big and a mix of Windows Forms windows and WPF user controls (always included using ElementHost). I already created a test app to reproduce the problem, but there it does not happen. I already stripped down the inclusion of the BIng Maps WPF Control in my big app to only the inclusion using ElementHost, like so:
<UserControl x:Class="xxxx.BingMapsUControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:maps="clr-namespace:Microsoft.Maps.MapControl.WPF;assembly=Microsoft.Maps.MapControl.WPF" xmlns:local="clr-namespace:xxxx" mc:Ignorable="d" d:DesignHeight="600" d:DesignWidth="800"> <Grid> <maps:Map x:Name="mapControl" Center="48.21,16.37" ZoomLevel="12" Grid.Row="0" CredentialsProvider="xxxx"> </maps:Map> </Grid> </UserControl>and in the corresponding Windows Forms form, it's only the ElementHost with the child 'BingMapsUControl'.
Do you have suggestions on how I could reproduce the problem in the test app?
Thanks! -

2022-04-22T09:26:12.103+00:00 Hi @Dsungaro ,
I tried to reproduce your problem with the following steps without success.- WPF User Control： 1.1 .Net Framework 4.8
1.2. Microsoft.Maps.MapControl.WPF Nuget installed.
1.3 User Control work well:
- Winform:
2.1 .Net Framework 4.8 2.2 Add the ElementHost control (in the toolbox) on the WinForm panel;
2.3 Add the WPF-generated control just now to the Child property in the ElementHost just now;
2.4 Work well：
What do you mean by "the map tiles are scrambled"?
Best Regards,
Jiale - WPF User Control： 1.1 .Net Framework 4.8

Could you give me an example that reproduces your current error?
By the way, try to create a new small project and see if you have the same problem.
Best Regards,

I'm sorry, I tried to create a new small project and reproduce the error, but there it works and the tiles are ok.
Therefore I'm not sure how I could give you an example...
Best regards, Anne -
