On Hyprland/Wayland the recording flow ran the countdown BEFORE the getDisplayMedia request — the portal picker blocked getUserMedia, so the video started late while cursor telemetry had already started, producing desynchronized cursor playback (and a frozen lead-in for the duration of the picker dialog). - Linux flow: request screen capture (portal picker) BEFORE the countdown - Cursor telemetry now starts together with the video capture - HYPRLAND_CURSOR_MEDIA_OFFSET_MS: 300 -> 0 (the calibration compensated for the wrong order; with capture-first it is no longer needed) Tested on: AMD Lucienne, Hyprland 0.56.2 — recording, save, editor and cursor/click sync all working in a single natural launch.
On Hyprland/Wayland the xdg-desktop-portal picker resolves getDisplayMedia BEFORE the user accepts: Electron's display media handler answers with the sentinel source immediately and the portal dialog runs asynchronously, so the countdown (and the MediaRecorder timeline with cursor telemetry) could start while the dialog was still open. Late acceptance produced video lagging behind cursor telemetry (~300ms desync from PipeWire negotiation); denial surfaced as a generic error dialog. - Gate the linux-portal flow on the FIRST delivered video frame (requestVideoFrameCallback on a detached video element) — the reliable user-accepted signal; denial surfaces as the track ending - Awaiting state drives the countdown overlay window via new IPC (begin/end-screen-permission-wait): same glass circle with spinner, 'waiting for screen permission' label and click/Esc cancel hint - start-countdown reuses a live overlay window so the accepted transition is spinner -> number without flashing - Portal denial now aborts with a quiet toast.info (recording.cancelledNoPermission) instead of the error dialog; the audio-path fallback no longer misclassifies denial as an audio failure - Record button disabled while awaiting permission; i18n keys mirrored across all 11 locales - Cursor capture epoch test updated: with the permission gate the legacy 300ms correction is no longer applied (telemetry and video start together) Scoped to selectedSource.id === 'screen:linux-portal'; Windows/macOS/X11 countdown paths unchanged.
Move the recording-timing diagnostics ([REC-DEBUG] cursor positions, evdev click/open/close traces) behind REC_DEBUG=1, default OFF, preserving their diagnostic value (50ms position throttle) for future investigations. Also documents why HYPRLAND_CURSOR_MEDIA_OFFSET_MS stays 0 now that the portal permission gate aligns telemetry with the video start.
…ndows Main-process side of the review round: - Post-grant overlay cancel race: a click on the overlay between the permission grant and start-countdown used to close the window while the renderer still started the countdown (recreating the window and recording despite the cancel). The controller now settles the granted state on cancel and start-countdown consults (and consumes) a short-lived gate that suppresses that start. - Orphan windows: cancel-countdown routes through the controller in every state (pending and granted), so no exit path leaves the transparent alwaysOnTop window open and invisibly blocking clicks. - Awaiting-state pull: the overlay lazily mounts after did-finish-load, so the awaiting event fired before its listener existed and the window opened blank (confirmed in runtime). New get-awaiting-screen-permission handler lets the overlay pull the current state on mount, mirroring get-active-countdown. - Geometry: the awaiting layout (spinner + labels behind the glass panel) needs more than the fixed 200x200 window; the window now resizes to 320x320 centered while awaiting and back to 200x200 for the countdown.
Renderer side of the review round: - Awaiting layout: single glass panel (same inline rgba(0,0,0,0.85) + blur(20px) + rounded-3xl styles already used by the countdown circle) holding the spinner, the waiting label and the cancel hint, so the hint text sits on the glass (contrast) and nothing overflows the resized window. No new hex colors — spinner uses the existing white rgba values, hint uses text-white/70. - Overlay mounts pulling the current awaiting state in addition to listening for changes (fixes the blank window when the event fired before the lazy component subscribed). - Cancelling from the app (overlay click / Esc) now shows the same quiet toast.info (recording.cancelledNoPermission) as a denial and tears down the portal request: stopping the captured tracks is the renderer-side cancellation for the pending xdg-desktop-portal request (accepting it afterwards has no effect). - The screen-permission IPC wait is now caught so a rejection resolves the gate as cancelled instead of surfacing an unhandled rejection. - Late failures after the grant (e.g. MediaRecorder rejecting the stream) and post-grant HUD cancels close the countdown window instead of leaving it orphaned.
The awaiting overlay hint promised 'click anywhere', but clicks only register inside the 320px overlay window. Reworded to 'click here' (PT-BR: 'Clique aqui ou pressione Esc para cancelar') across all 11 locales, plus the renderer fallback string. Text-only change.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Parse the capability word with BigInt to keep 64-bit precision.
capabilities/key exposes 64-bit words in hex. Number.parseInt(word, 16) returns a double, and >>> applies ToUint32. For a word value above 2^53 the low bits are already lost before the shift, so the BTN_LEFT bit can read as 0. The device is then skipped and its clicks are never captured, with no error. Word selection and the bit index are correct; only the numeric width is unsafe.
🐛 Proposed fix using BigInt
export function hasMouseButtonCapability(keyCapabilities: string): boolean {
const words = keyCapabilities.trim().split(/\s+/);
const word = words[words.length - 1 - Math.floor(BTN_LEFT / 64)];
if (!word) {
return false;

Keep evdev capture active when uiohook is unavailable.
On Hyprland, evdev capture starts before loadUiohookModule(). These calls stop it when uiohook is unusable or throws. As a result, the fallback cannot record mouse buttons on the Wayland path where uiohook fails.
Keep the existing evdev cleanup callback installed. Stop evdev only when interaction capture stops.

A late getAwaitingScreenPermission result can re-show the spinner after the grant.
The initial pull and the onAwaitingScreenPermission subscription race. If the grant arrives while the pull is in flight, the event sets awaiting to false and the resolved pull then sets it back to true. The guard only ever writes true, so nothing corrects it. A countdown tick clears the state, but with countdownDelay === 0 no tick arrives.
Ignore the pull result once an event has updated the state.

});Set receivedAwaitingEvent = true inside the onAwaitingScreenPermission handler, and move both the pull and the subscription into the same effect so they share the flag.

Use useScopedT("launch") for the recording translations. The unscoped translator resolves recording.* to common, but these keys exist under launch.recording. The three call sites therefore use English fallbacks instead of localized values.

With countdownDelay === 0 the portal path leaves the overlay window open.
electron/ipc/register/settings.ts (lines 90-98) keeps the countdown window alive on a grant, because start-countdown is expected to reuse it. This branch skips startCountdown when countdownDelay === 0, and no other call closes the window on the success path. The transparent alwaysOnTop window then stays over the screen for the whole recording. Your own comment at Line 2431 states that this window invisibly blocks clicks.
Close the window explicitly when no countdown runs.

Problem
On Hyprland/Wayland (portal screen source), the countdown ran in parallel with the xdg-desktop-portal permission dialog. If the user accepted after the countdown finished, recording started with the video stream late vs cursor telemetry — desynchronized cursor/clicks in the editor (~300ms+). Denying the permission showed a generic error dialog.
Root cause
getDisplayMediain the Linux portal flow resolves immediately (the source handler returns ascreen:0:0sentinel while the system dialog is still open) — the previous order fix assumed it blocked until acceptance. Reliable acceptance signal: first video frame (requestVideoFrameCallback); denial = trackended.Solution (gated to
screen:linux-portalonly)toast.infoinstead of error dialog; portal request torn downREC_DEBUG=1(off by default)Cross-OS safety
Windows/macOS/X11 untouched: all flow changes gated by the portal source; new IPC is inert outside the Linux portal flow; classic countdown paths equivalent to main.
Validation
