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 |
