Root-cause hypothesis: fx_vst_bridge parked embed window offscreen (-20000,-20000)
during VST3 editor attach; Ozone 11 GL init null-derefs (c0000005 in
iZOzone11Core.dll+18f6b92) on Intel ICD. Reaper hosts window on-screen -> OK.
- RenderFxJob.cpp: env toggle SF_FXGUI_ATTACH_ONSCREEN=1 -> SetWindowPos(100,100)
before fxGuiLoadAttach, park back offscreen after attach succeeds
- main_fx.cpp: FxCrashDumpHandler prints [CRASH] in <module>+0x<offset> and
[CRASH] minidump: <path> so logs name the faulting plugin DLL directly
- app.jsx VstGuiEmbed: frameLoadedRef + 90s watchdog -> onDead if bridge alive
but no frame (no more infinite 'Dang tai plugin VST...' flash); clearer onDead
toasts with %TEMP%\sf_dumps\fx_bridge_crash_*.dmp hint (track + master)
- rebuild fx_vst_bridge + daw_vst_bridge, NSIS/MSI v=202609021809
- SandboxVst2Host::loadSerializedState: queuePreset non-blocking (byte-identical
echo never matched -> waitApply always burned 20s TIMEOUT on the audio thread;
VST2 restore runs via runOnMain so every startup silenced ALL audio ~20s = Qin
'failed that su'). Bridge now holds reloading + defers saveStateJob until the
child republishes a different chunk (clobber protection, no audio block).
- sf-fx-realtime clear_queue('loop'): truncate old tail to KEEP=4 blocks
(~21ms) instead of keeping FILL 24 (~128ms) -> wrap downbeat no longer ~110ms
late; skipFade crossfade masks the truncation jump, seam crossfade recount.

Real-input clicks were landing in whatever window sat above the anchored
plugin window (foreground Chrome in tests) — WindowFromPoint at the click
point returned the browser, so the editor never saw the input. Attach to
the foreground thread, SetForegroundWindow + BringWindowToTop before the
click (still non-TOPMOST — no floating regression from 80c663e).
