Billionmail/BillionMailcap-v0.4.83Apr 4, 2026by github-actions[bot]

AI Summary

The update focuses on stabilizing audio playback across speed changes and fixing macOS-specific issues like encoder drift and startup race conditions. It also addresses UI layering and camera cleanup problems.

Key Highlights

Timeline audio now renders correctly across speed change boundaries.
Fixed macOS MP4 encoder audio drift based on effective video PTS.
Window layering fixed to prevent Cap from unexpectedly stealing focus.
Camera preview compositing fixed for GPUs with limited alpha mode support.

Full Release Notes

- **Audio across speed segments** — Timeline audio now renders correctly across speed change boundaries. Previously, applying speed changes could cause audio to cut out or glitch at segment edges.
- **Audio playback stability** — Fixed a crash that could occur when starting audio playback in certain editor states.
- **Audio drift correction** — The macOS MP4 encoder audio drift guard is now based on effective video PTS, fixing audio sync drift that could occur with external microphones.
- **Sensitive mask scaling** — Pixelation masks now scale proportionally with output height, so blurred regions stay correctly sized when exporting at different resolutions.
- **FFmpeg decoder reliability** — Future frames are now ignored during decoder fallback, and the frame reuse window is wider, preventing wrong frames from appearing during seeking or playback near cuts.
- **Export fix for recovered projects** — Recovered projects no longer force the FFmpeg decoder path, fixing export failures that could occur on recordings restored from a crash.
- **macOS startup race fix** — Main window setup is deferred until the UI reports ready, and uploads resume correctly after the ready listener installs. This fixes a class of startup hangs and stalled uploads on macOS.
- **Window layering fix** — The main panel is no longer forced above other windows when shown, fixing cases where Cap would unexpectedly steal focus.
- **macOS dock icon sync** — Dock icon visibility now correctly follows the hide-dock-icon setting and updates when windows open or close.
- **Camera cleanup on exit** — Camera preview shutdown always begins on app exit, and macOS camera window teardown is skipped during exit cleanup to prevent quit-time crashes.
- **Windows editor reopen** — Editor windows on Windows now correctly reopen after being closed, matching the existing macOS behavior.
- **Hex color input** — RGB hex input is now gated until the full digit count is entered, preventing partial color values from being applied mid-typing.
- **Camera preview compositing** — The camera preview now selects a supported wgpu composite alpha mode, fixing rendering artifacts on GPUs that don't support the previously hardcoded mode.
