Reduced sharpness and choppy playback in full talking-head mode

When recording in full talking-head mode (just me on camera, no screen share / no on-screen content), the video isn't sharp and playback isn't smooth — there's noticeable softness and slight stuttering. This doesn't happen on recordings that include a screen-share portion, so it seems specific to the talking-head layout. Could you check whether the talking-head mode is being rendered at a lower bitrate or frame rate? Higher sharpness and smoother playback here would be a big improvement. Happy to share resolution, FPS setting, and browser/OS if that helps reproduce it.
