ERROR_GRAPHICS_POLLING_TOO_FREQUENTLY
Locate the failing graphics boundary: graphics polling too frequently
ERROR_GRAPHICS_POLLING_TOO_FREQUENTLY, value 0x40262439, is produced by graphics info when the driver requested child-status polling again before the allowed interval at the same polling level. The investigation should stay attached to display-child polling cadence and to the exact generation in which it was obtained.
Informational graphics results are part of WDDM control flow. They must not automatically be surfaced as a fatal application error or translated into an unrelated Win32 code.
Evidence that makes the result actionable
| Capture item | Why it matters |
|---|---|
| Supporting trace | kernel graphics ETW, callback name, child or allocation identifiers, PnP state and the first returned NTSTATUS/HRESULT |
| Object identity | display-child polling cadence |
| Rejected condition | the driver requested child-status polling again before the allowed interval at the same polling level |
| What to capture | child UID, polling level, timestamps, hot-plug awareness and the caller loop that requested the poll |
| Current graph state | WDDM kernel/miniport callback and the transient object state carried by that callback |
A controlled comparison
- Capture the failing state. Record child UID, polling level, timestamps, hot-plug awareness and the caller loop that requested the poll.
- Increase the interval in a test driver path and compare the returned status under identical connector state.
The comparison with ERROR_GRAPHICS_UNKNOWN_CHILD_STATUS is especially useful: ERROR_GRAPHICS_UNKNOWN_CHILD_STATUS concerns result reliability, not polling frequency.
Correction and proof
Rate-limit polling and prefer interruptible hot-plug notification where the hardware supports it.
- debug-layer, ETW or driver diagnostics no longer report the rejected display-child polling cadence contract during the same scenario.
Implementation notes
Log kernel graphics ETW, callback name, child or allocation identifiers, PnP state and the first returned NTSTATUS/HRESULT.
