UCEERR_CTXSTACKFRSTTARGETNULL
UCEERR_CTXSTACKFRSTTARGETNULL is a Windows User Composition Engine (UCE) HRESULT. It indicates that the composition engine expected an initial target in its context stack but found no usable target.
What to check for UCEERR_CTXSTACKFRSTTARGETNULL
- Check window creation, display-target availability, and shutdown timing around the rendering operation.
- Avoid invoking rendering-related work after the target window has been closed or disconnected.
- Look for earlier composition or device failures that could have invalidated the target.
