Map freezes when returning from CTRL+ALT+DEL screen.

Hello,

I have a ArcGISRuntime for .NET (100.6) applications that contains many dynamic GraphicsOverlays. When I return from the CTRL+ALT+DEL screen, the application freezes, sometimes leaving the map black, sometimes not. The application does the same thing when I change desktops and return. Has this behavior been reported in the past?

The windows application log is as follow:

Application: xxx.exe Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception.

Yes, a relatively similar issue was reported in the past. Blank map when WPF is in software rendering mode and has been fixed in 100.5 release. But every use case is different. The most recent release is 100.7. Could you give that a try and see if it makes any improvement/difference?

This is still happening with 100.8.

That's not a good news. I think we would need some more info or preferably a repro app to check what is going on.

There are so many factors : What does the app do? How many dynamic overlays are there? what kinds of graphics are there ? what kind of symbols are being used? What state in the app in before display locks out?

It can be challenging to determine the cause without a reproducible case.
