UI_E_DIFFERENT_OWNER
The scope of UI_E_DIFFERENT_OWNER is Windows Animation Manager: an object was supplied to an animation owner other than the one that created it. Preserve 0x802A0009 beside the returning call before cleanup or retry creates a more generic secondary failure.
Read the boundary first
When it is returned, Windows Animation is a stateful COM subsystem. During a this result investigation, animation variables, transitions and storyboards are created under a manager, scheduled against a monotonic animation time, updated before drawing, and eventually sealed or released. A visible glitch can therefore be downstream of a lifecycle, ownership, timeline, callback, or numeric contract failure.
During a this result investigation, animation objects carry manager or storyboard ownership. Mixing transitions, variables, keyframes, or timers across independently created managers can leave COM interfaces valid while violating the graph’s ownership domain.
The first owner to inspect is the animation manager, storyboard, transition, timer, or callback that returned the HRESULT.
Keep neighboring conditions separate
When it is returned, UI_E_TRANSITION_ALREADY_USED is reuse within storyboard membership; DIFFERENT_OWNER is a broader ownership mismatch.
Do not compare only COM pointer values or assume all managers are interchangeable.
Incident record for this HRESULT
| Capture | Diagnostic value |
|---|---|
| Owner identity for both objects for this HRESULT. | This provides a stable comparison across retries or another machine and helps test the Windows Animation Manager boundary. |
| Creation factory for the parameter for this HRESULT. | This identifies the exact object or resource generation involved and helps test the Windows Animation Manager boundary. |
| Manager generation and thread for this HRESULT. | This places the failure on the lifecycle or transaction timeline and helps test the Windows Animation Manager boundary. |
| Cross-component cache or singleton source for this HRESULT. | This separates caller input from environment and service state and helps test the Windows Animation Manager boundary. |
Reproduce without destroying evidence
The investigation should change one variable at a time and keep the original failing sample.
- First: Tag cached objects with their creating manager.
- Next: Create dependent objects from the same owner.
- Then: Remove global transition or keyframe caches as a control.
- Finally: Rebuild the entire minimal graph under one manager.
Three useful controls
- Fresh storyboard or animation object: for this HRESULT, a changed result separates retained object, connection, path, host, or device state from the original input. Hold constant: for this HRESULT, keep the timeline, transitions, and manager version fixed.
- Reduced failing operation: If this result follows the reduced step, the rejecting transition is localized. Hold constant: for this HRESULT, retain owner identity for both objects and remove only unrelated work.
- Targeted corrective control: Use this as a diagnostic branch rather than a blanket workaround: tag cached objects with their creating manager. Hold constant: for this HRESULT, keep the original failing sample available for the final regression test.
Definition of done
Closure for this HRESULT requires the graph is assembled from one owner generation and survives repeated create-schedule-release cycles; then repeat the next lifecycle operation to detect stale state.
