+# v3.3.106 — intermittent white-screen on startup (RDP/VM GPU) + export filename
+
+Two asks. (A) White screen: user sometimes gets a PURE-WHITE window on start (no error banner, NOT even the
+static menu bar) on a 12-vCPU Windows VM over RemoteDesktop. Workflow wn2k04x5t (2 agents + adversarial verify)
+nailed it by one airtight deduction: the BrowserWindow backgroundColor is DARK (#16181c, main.js:1228), so
+"white" can NEVER be an un-painted/loading/failed state — those all show DARK. Pure-white + no menu bar + no
+banner + SILENT eliminates every DOM/init/CSS/load mode (each leaves the dark styled shell, unstyled-black-on-
+white menu text, or the red init().catch banner) → the ONLY match is a GPU/compositor surface failure on the
+RDP virtual display adapter. Confirmed: NO disableHardwareAcceleration / disable-gpu / appendSwitch ANYWHERE,
+and child-process-gone (GPU) is log-only (matches the silent symptom) while render-process-gone pops a dialog.
+Renderer has ZERO WebGL/canvas/video (audited) → software compositing costs ~nothing and doesn't undo the perf
+work; a webContents.reload() doesn't disrupt uploads (uploadManager lives in main, torn down only on quit).
+Watchdog REJECTED: the GPU mode lets init complete, so an init-complete signal wouldn't detect the white screen.
+
+SHIPPED v3.3.106 (main.js — adversary's safe subset):
+- app.disableHardwareAcceleration() at module top (before app.whenReady) GATED on RDP (process.env.SESSIONNAME
+  matches /^RDP/) OR a persisted gpu-disabled.flag (in userData). Zero-regression for local/console users.
+- Auto-heal: on a GPU child-process-gone, write gpu-disabled.flag → next launch disables HW accel even if the
+  RDP gate missed (covers VM-via-console / bad virtual GPU). Self-healing after at most one white screen.
+- Kept the child-process-gone/render-process-gone/did-fail-load instrumentation to CONFIRM on the server log
+  (caveat: root cause is the standard RDP-GPU bet, not yet confirmed on the affected machine — next white-start
+  log shows CHILD PROCESS GONE type=GPU = confirmed).
+- (B) export-backup defaultPath: multi-hoster-backup-YYYY-MM-DD.mhu → DD-MM-YYYY-multihoster-backup.mhu.
+409 tests pass, clean boot (guard inert on non-RDP dev machine).
+
+DEFERRED (perf polish, workflow w5o2rpffx design ready): history JSONL + batch-start residual.
