Windows App SDK 2.6.5

[agniuks]

Windows App SDK 2.6.5 delivers targeted fixes for rendering, window composition, system backdrops, and packaged app installation.

Bug fixes

Bug fix	Runtime Compatibility Change
Fixed rendering corruption that could occur on systems with multiple graphics adapters or monitors.	N/A, rendering-region fix
Fixed an E_NOINTERFACE crash when enabling the System Composition Engine on Windows builds that lack the required interfaces. The runtime now uses the lifted compositor on those builds.	N/A, operating system capability detection fix
Fixed an issue where window backgrounds and GDI controls could become unexpectedly transparent on Windows 10, including apps hosting XAML islands.	N/A, window composition ABI fix
Reverted the system backdrop change introduced in 2.6.4 to address wrong-thread exceptions. System backdrops for content islands and XAML windows are not supported when using the System Composition Engine in this release.	N/A, revert of a previously contained change
Fixed an issue where app-extension registration metadata generation returned E_NOTIMPL, which could prevent packaged apps from installing.	N/A, missing implementation fix
