fix: throttle screen capture to reduce system lag#11
Merged
Conversation
The screen reader thread was capturing screenshots in a tight loop with no frame rate limit, causing high CPU and memory pressure. With action- gated video, only the most recent screenshot matters when an action occurs, so capturing at 100+ fps was pure waste. Add SCREEN_CAPTURE_FPS config (default: 10 fps). The throttle sleeps for the remainder of the frame interval after each capture. Set to 0 for unlimited (legacy behavior). Also available as screen_capture_fps param on Recorder constructor and RecordingConfig. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
