…x (X11) - Fix GPU crash on Linux by removing incompatible --use-gl=egl switch - Fix HUD overlay expansion when clicking 3-dots/timer on Linux - Include Linux static ffprobe in electron-builder package configuration - Fix InvalidStateError during MediaRecorder start by adding robust codec fallbacks - Disable WebRTCPipeWireCapturer on Linux X11 so screen capture works directly without DBus portal timeouts - Ensure desktopCapturer sources are resolved properly on Linux X11 sessions - Prioritize WebGL renderer in modern frame export to prevent WebGPU texture limit crashes - Add .m4a to supported local media types

2213-2216: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low valueExtract the screen-recorder handlers into a helper.
The loop has one source copy of the handlers, but each candidate
MediaRecorderreceives new handler closures. Move the assignments intocreateScreenRecorderHandlers(recorder, candidateMimeType)to keep the longonstopfinalization path out of the retry loop without changing behavior.🤖 Prompt for AI Agents

Inline comments:
In `@electron/main.ts`:
- Around line 1063-1066: Update the display-capture request target resolution
near the existing isLiveFrame/frame conditional to use
electronWebContents.fromFrame(frame) for live frames instead of reading
frame.webContents or falling back to hudWindow.webContents; reject or deny the
request when frame resolution fails, while preserving the HUD webContents path
for non-frame requests.
In `@src/hooks/useScreenRecorder.ts`:
- Around line 1142-1144: Update the fallback handler wiring in the webcam
recorder flow so reused handlers operate on the active fbRecorder and its MIME
type rather than the original recorder’s captured values. Refactor the handler
setup around prepareWebcamRecorder into a factory or equivalent parameterized by
recorder and MIME type, then use it for both recorders while preserving the
existing extension, Blob type, and WebM duration-fix behavior.
- Line 1176: Update prepareRecordingStart to query getLinuxWindowSystem before
fetching a fallback screen source; on Wayland, use LINUX_PORTAL_SOURCE directly
instead of calling window.electronAPI.getSources, while preserving source
enumeration for other window systems.
- Around line 2011-2013: Update the display-capture flow around
resolveBrowserCaptureSource and getSelectedSourceId so the resolved live source
ID is preserved and used by the Electron handler before getDisplayMedia
executes. Ensure a matching display_id is selected instead of allowing a missing
ID to fall back to sources[0], while preserving the existing capture behavior
for valid selections.
