STATUS_GRAPHICS_PRESENT_MODE_CHANGED
STATUS_GRAPHICS_PRESENT_MODE_CHANGED means that the presentation operation occurred, but the desktop mode changed as part of the same period. The result is different from a simple failed present: a frame may have reached the presentation path, while assumptions about output size, timing, color format, or target mode became stale.
Record the mode and topology before the request and query them again after this status. The relevant state is the display configuration actually active after the operation, not only the mode stored by the application before it submitted the frame.
useful split
- A resolution, refresh, HDR, rotation, or target change points to display configuration work.
- A desktop attach or dock event points to target enumeration and topology work.
- A switch between presentation modes points to an application lifecycle issue around swap-chain or display-resource recreation.
Do not report this status as proof of data corruption or GPU reset. First re-enumerate the active display state, update resources that are mode-dependent, and preserve the original timing of the mode-change event.
