ERROR_GRAPHICS_START_DEFERRED

Why this is not a generic GPU failure: graphics start deferred

Windows reports ERROR_GRAPHICS_START_DEFERRED (0x4026243A) at the graphics info checkpoint. Here, adapter start was postponed because a prerequisite state transition had not completed. That narrows the first investigation to display-adapter PnP start scheduling instead of the entire GPU stack.

ERROR_GRAPHICS_START_DEFERRED: Informational graphics results are part of WDDM control flow. For ERROR_GRAPHICS_START_DEFERRED, They must not automatically be surfaced as a fatal application error or translated into an unrelated Win32 code. For ERROR_GRAPHICS_START_DEFERRED, the built-in one-line message identifies the immediate result; diagnosis also needs the producing API, object ownership and the display generation current at the time.

The smallest evidence set

Capture itemWhy it matters for ERROR_GRAPHICS_START_DEFERRED
Object identitydisplay-adapter PnP start scheduling
Rejected boundaryadapter start was postponed because a prerequisite state transition had not completed
Decisive capturedevice instance, PnP problem code, parent and dependency states, power transition and start-attempt order
Current graph stateWDDM kernel/miniport callback and the transient object state carried by that callback
Supporting tracekernel graphics ETW, callback name, child or allocation identifiers, PnP state and the first returned NTSTATUS/HRESULT

For ERROR_GRAPHICS_START_DEFERRED, preserve the unsigned HRESULT, symbolic name, first failing API and timestamp in one record. If cleanup later fails too, keep that secondary result separately from ERROR_GRAPHICS_START_DEFERRED.

A/B test for the exact condition

  1. Freeze the ERROR_GRAPHICS_START_DEFERRED generation. Record device instance, PnP problem code, parent and dependency states, power transition and start-attempt order. Before diagnosing ERROR_GRAPHICS_START_DEFERRED, do not resize, hot-plug, recreate or release the object under examination.
  2. Run the narrow ERROR_GRAPHICS_START_DEFERRED comparison. observe a normal boot/start trace and compare with the sequence that triggers deferral. During the ERROR_GRAPHICS_START_DEFERRED comparison, keep every driver, monitor, resource format and unrelated policy unchanged.
  3. Observe the layer after ERROR_GRAPHICS_START_DEFERRED. For ERROR_GRAPHICS_START_DEFERRED, if the exact check passes, record the next HRESULT or visible outcome. A different downstream result shows that the ERROR_GRAPHICS_START_DEFERRED boundary was crossed.
  4. Repeat ERROR_GRAPHICS_START_DEFERRED through a lifecycle transition. For ERROR_GRAPHICS_START_DEFERRED, exercise one relevant resize, mode switch, device recreation, hot-plug or session change and confirm that this result does not reuse stale handles.

The comparison with ERROR_GRAPHICS_LEADLINK_START_DEFERRED is especially useful: ERROR_GRAPHICS_LEADLINK_START_DEFERRED is specific to the lead member of a linked-adapter chain. For ERROR_GRAPHICS_START_DEFERRED, recording both names prevents a broad “graphics error” label from merging distinct ownership, capability and lifetime problems.

Safe remediation

Let the prerequisite transition complete and remove ordering defects in the driver or device stack. Repair of ERROR_GRAPHICS_START_DEFERRED is complete only when the original call succeeds or returns its documented nonfatal status and the same lifetime test remains correct after a second display transition.

  • The ERROR_GRAPHICS_START_DEFERRED trace identifies one producing API and one current graphics object, rather than only the final UI symptom.
  • The passing run changes exactly the condition described for ERROR_GRAPHICS_START_DEFERRED; unrelated adapter, monitor and application state remains unchanged.
  • For ERROR_GRAPHICS_START_DEFERRED, debug-layer, ETW or driver diagnostics no longer report the rejected display-adapter PnP start scheduling contract during the same scenario.
  • The application handles recurrence of ERROR_GRAPHICS_START_DEFERRED without an unbounded retry loop, leaked resource, duplicate composition target or stale topology handle.

Implementation notes for ERROR_GRAPHICS_START_DEFERRED

For ERROR_GRAPHICS_START_DEFERRED, log kernel graphics ETW, callback name, child or allocation identifiers, PnP state and the first returned NTSTATUS/HRESULT. When the ERROR_GRAPHICS_START_DEFERRED path returns a count, size, status flag or replacement object, retain it even on a nonfatal result because it can direct the next call.

A production fallback for ERROR_GRAPHICS_START_DEFERRED should be explicit: pause rendering, re-enumerate, rebuild one cache entry, recreate a device, or decline a protected path only when this layer calls for that action. Reinstalling every display component, deleting all caches or forcing a resolution change is not an evidence-based fix for ERROR_GRAPHICS_START_DEFERRED.
