[Problem/Bug]: WebView2CompositionControl triggers the COMException UCEERR_RENDERTHREADFAILURE (0x88980406) when the docking station or even the monitor is unplugged.

What happened?

If we have more than one monitor connected to the computer and a WPF application that contains WebView2CompositionControl is currently being rendered on the screens, and we then disconnect the docking station or the monitor, a COMException UCEERR_RENDERTHREADFAILURE (0x88980406) is thrown, causing the application to crash.

Hi, @ccdninja!

It seems that your issue contains the word "crash". If you have not already, could you attach a crash dump as a comment?

WV2 crash dumps are located in a subfolder of the app's user data folder (UDF): <UDF>\EBWebView\Crashpad\reports\. By default, the user data folder is created in the app's folder with a name like <App Exe Name>.exe.WebView2. Refer to Crash Diagnostics for more information.

Thank you for your cooperation!

Unfortunately, the specified folders are empty.

Any updates on this? We just updated the Microsoft.Web.WebView2 package from version "1.0.3351.48" to version "1.0.3405.78" and now have the same issue in our application.
@champnic could you have a look at this please?
