UCEERR_GRAPHICSSTREAMUNAVAILABLE
UCEERR_GRAPHICSSTREAMUNAVAILABLE is a Windows User Composition Engine (UCE) HRESULT. It indicates that the engine cannot obtain the graphics stream required for the requested composition operation.
What to check for UCEERR_GRAPHICSSTREAMUNAVAILABLE
- Check graphics-device state, display session availability, and target-window lifetime.
- Recreate device-dependent resources after a reset or a detected rendering-channel failure.
- Test with simpler graphics content to distinguish a resource shortage from a driver issue.

Diagnostic interpretation
This result has the HRESULT value 0x88980419. AllStat records the condition as “it”.
Evidence to capture
- Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions this result or the uceerr / graphicsstreamunavailable operation.
- Preserve the first failure in the call chain; a later HRESULT can describe cleanup rather than the original uceerr / graphicsstreamunavailable condition.
Retry and recovery
Retry this result only when the owning API documents a transient state or after the condition described as “it” has changed.
