STATUS_GRAPHICS_WINDOWLESS_PRESENT_DISABLED
STATUS_GRAPHICS_WINDOWLESS_PRESENT_DISABLED means that the requested windowless presentation path was disabled because the desktop windowing-management subsystem was off. Windowless presentation depends on a composition/redirection path; it is not equivalent to ordinary off-screen rendering.
Record whether the application requested a windowless path intentionally, which Windows generation is involved, and whether the caller is running in an interactive desktop. On current Windows versions, composition is not normally toggled by applications, so an unexpected result should prompt investigation of environment and compatibility conditions rather than a generic instruction to enable DWM.
Diagnostic focus
- Separate the requirement for redirected windowless presentation from the ability to render into an off-screen surface.
- Check session and desktop context before treating this as an adapter fault.
- Use a presentation mode that the application and platform explicitly support when redirection is not available.
This status is most useful when logged together with the requested presentation mode and the composition state observed immediately before the request.
