## WPF windows are rendered without clipping when extending outside a single monitor

### Scope
Minor

### Version Introduced
4.6

### Source Analyzer Status
Not planned

### Change Description
In the .NET Framework 4.6 running on Windows 8 and above, the entire window is rendered without clipping when it extends outside of single display in a multi-monitor scenario. This is different from previous versions of the .NET Framework which would clip WPF windows that extended beyond a single display.

- [ ] Quirked
- [ ] Build-time break

### Recommended Action
This behavior (whether to clip or not) can be explicitly set using the `<EnableMultiMonitorDisplayClipping>` element in `<appSettings>` in an application's configuration file, or by setting the `EnableMultiMonitorDisplayClipping` property at app startup.

### Affected APIs
* Not detectable via API analysis
