…en asked MF_READWRITE_ENABLE_HARDWARE_TRANSFORMS defaults to FALSE, and the "default" sink-writer path (no preferSoftwareEncoder, no OPENSCREEN_WGC_ENABLE_DXGI_INPUT) never set it. So every plain recording ran on the software H.264 encoder regardless of what GPU the machine had -- the DXGI path was the only one that ever asked for hardware. On a fast CPU that's invisible; on the older machines in #460 (a 6th-gen i3, an i5-4590 with HD 4600) it's slow enough to blow the 50-60s stop-shutdown budget and lose the whole recording to a "Timed out waiting for native Windows capture to stop" failure. createSinkWriter now asks for hardware transforms whenever software is not forced, DXGI device manager or not. Verified against the real compiled helper: the default path went from videoEncoderRuntime "software" to "hardware" on this machine, with no other flags set. That uncovered a second, known issue the DXGI path had already fixed once: hardware MFTs default to constant bitrate, which spends the full configured budget doing nothing on a static screen. applyHardwareRateControl's VBR fix was gated on the DXGI path alone; it now runs whenever hardware transforms were requested, matching the wider condition above. Added videoEncoderRuntime ("hardware"/"software"/"unknown") to the encoder-selection event so a bug report can tell these two failure shapes apart going forward: a real hardware encoder stalling on a bad driver, versus every recording quietly running through software regardless of what hardware is on the machine. It introspects the sink writer's own resolved transform pipeline (IMFSinkWriterEx::GetTransformForStream) rather than trusting which path was configured, since MF is free to hand back software even when hardware was requested. Verified end to end on real hardware: compiled with MSVC/CMake, ran the actual helper through the full test matrix (default, software-encoder, DXGI, window, system-audio, microphone, audio-timeline, mic-selection) with no regressions. One accepted trade-off, confirmed back-to-back on this machine: hardware output ran roughly 5x larger than software for the same content even with VBR correctly engaged (8.7 Mbps vs 1.7 Mbps) -- a real rate-distortion difference between the two encoders, not a rate-control bug, and worth the CPU relief and stop-reliability it buys on weak machines.

electron/ipc/handlers.ts and preload.ts fully implemented saveDiagnostic, and "Save Diagnostics" was localized into all 13 languages, but nothing in the app ever called it -- no button, no menu item, no keyboard shortcut. Found this while working out how to answer a #460 reporter's own question about where to find the diagnostic log: there was no working answer. Extracted the file-writing logic into an exported exportDiagnosticFile, shared by the existing IPC handler and three new entry points in main.ts: the tray's context menu (idle state), the Windows/Linux Help menu, and the macOS app menu. The tray one matters most for capture bugs like #460 -- it's reachable without opening any window, which is exactly the state a HUD is usually in right after a recording fails to stop. Reused "Save Diagnostics"'s existing translations (copied from the otherwise orphaned settings.support.saveDiagnostics key into common.json's actions) rather than inventing new strings across 13 locales. Verified: tsc --noEmit clean, biome clean, full suite (2161 tests) passes, i18n:check passes. Did not launch the dev Electron app -- native menu/tray changes aren't observable through the browser preview tooling, and a second instance risks the single-instance lock other active worktrees hold.

- Around line 549-558: Update runSaveDiagnostics to handle unsuccessful export
results: when result.success is false and result.canceled is not true, display
an error to the user using the existing application error-notification
mechanism; preserve showing the exported file for successful results and
silently ignore cancellations.
In `@electron/native/wgc-capture/src/mf_encoder.cpp`:
- Around line 407-418: Update the comment above the encoder hardware-detection
logic to reflect that the default path requests hardware transforms when
software encoding is not forced, but Media Foundation may still resolve that
request to a software MFT. Keep the explanation of checking the constructed
pipeline via GetTransformForStream unchanged.
In `@src/i18n/locales/ko-KR/common.json`:
- Line 44: Update the saveDiagnostics locale entry in ko-KR so it uses the
approved Korean translation “진단 정보 저장” instead of the English label.

Three findings, all confirmed against current code: - runSaveDiagnostics silently did nothing when exportDiagnosticFile resolved with success:false (a write failure after the user already picked a save location) -- it only handled the success and implicit-reject cases, so a real failure read as the menu action doing nothing. Now shows an error dialog with the underlying message as detail, cancellation still a no-op. - detectVideoEncoderRuntime's doc comment in mf_encoder.cpp still said the default path asks for no hardware-transform attribute at all, which was true when it was written but stopped being true once the default path started requesting MF_READWRITE_ENABLE_HARDWARE_TRANSFORMS. Updated to say what's actually true now: it's a request Media Foundation can still answer with software, which is why the runtime still has to be checked after the fact rather than assumed from the path. - ko-KR's actions.saveDiagnostics carried the English label because it was copied from settings.support.saveDiagnostics, which was itself never translated for Korean. Applied CodeRabbit's suggested translation. Verified: tsc --noEmit clean, biome clean, i18n:check passes, native helper rebuilds clean on MSVC, full suite (2161 tests) passes.
