DXGI_STATUS_MODE_CHANGE_IN_PROGRESS
What Windows rejected: status mode change in progress
DXGI_STATUS_MODE_CHANGE_IN_PROGRESS, value 0x087A0008, is produced by dxgi status when another device was changing full-screen or windowed mode when the caller requested a conflicting operation. The investigation should stay attached to exclusive-mode transition arbitration and to the exact generation in which it was obtained.
A DXGI status can describe a successful or temporarily invisible presentation. Converting every non-S_OK value into device recreation destroys useful state and can create a full-screen transition loop.
Build a useful diagnostic record
| Capture item | Why it matters |
|---|---|
| Rejected condition | another device was changing full-screen or windowed mode when the caller requested a conflicting operation |
| What to capture | SetFullscreenState and ResizeTarget call order, owning HWND, output identity, message-pump state and competing process activity |
| Current graph state | swap chain, target window, output and Present call |
| Supporting trace | Present/Present1 result history, WM_SIZE or WM_DISPLAYCHANGE messages, swap-chain description and current IDXGIOutput identity |
| Object identity | exclusive-mode transition arbitration |
Separate state from capability
- Capture the failing state. Record SetFullscreenState and ResizeTarget call order, owning HWND, output identity, message-pump state and competing process activity.
- Start one controlled full-screen transition and issue the second request before the first transition completes.
The comparison with DXGI_ERROR_MODE_CHANGE_IN_PROGRESS is especially useful: DXGI_ERROR_MODE_CHANGE_IN_PROGRESS is a failing API result; this status can be returned as nonfatal transition feedback.
Verify the repaired path
Serialize mode changes, keep the window message pump responsive and retry after the transition settles.
- debug-layer, ETW or driver diagnostics no longer report the rejected exclusive-mode transition arbitration contract during the same scenario.
