MILERR_MISMATCHED_SIZE
MILERR_MISMATCHED_SIZE is a Windows Media Integration Layer (MIL) HRESULT. It indicates that a rendering resource, surface, bitmap, or related object has dimensions inconsistent with the request.
What to check for MILERR_MISMATCHED_SIZE
- Compare source, destination, stride, and DPI-adjusted dimensions using the same unit system.
- Recreate size-dependent resources after resizing a window, monitor, or render target.
- Check integer rounding and pixel-format alignment when converting logical layout size to a backing surface size.

Diagnostic interpretation of MILERR_MISMATCHED_SIZE
MILERR_MISMATCHED_SIZE has the HRESULT value 0x88980090. AllStat records the condition as “The size of the object does not match the expected size.”. For MILERR_MISMATCHED_SIZE, in practice, interpret that wording at the boundary owned by the Windows component or COM interface that returned the HRESULT, rather than treating the value as a generic Windows message.
Evidence to capture for MILERR_MISMATCHED_SIZE
- Record the exact COM method or Windows API, its input object, the calling thread, and the full 0x88980090 value before a wrapper converts it to an exception or Boolean result.
- Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions MILERR_MISMATCHED_SIZE or the milerr / mismatched / size operation.
- Reproduce MILERR_MISMATCHED_SIZE with the smallest valid input and note whether the result changes with identity, architecture, service state, or target object.
Retry and recovery for MILERR_MISMATCHED_SIZE
Retry MILERR_MISMATCHED_SIZE only when the owning API documents a transient state or after the condition described as “The size of the object does not match the expected size.” has changed. For MILERR_MISMATCHED_SIZE, configuration, policy, format, and authorization failures normally require correction first; an immediate loop can hide the original call site and add secondary errors.
