tmux visual-bell and external terminal multiplexer alert integration

Visual Alert Configuration Across Terminal Multiplexers

tmux provides built-in mechanisms for generating visual alerts through the visual-bell and visual-activity options, which can signal events like process completion or window activity. These alerts operate at the tmux level, triggering screen highlights or title changes based on configured behaviors. However, when another terminal multiplexer or enhanced terminal emulator sits between tmux and the user's terminal, the alert delivery chain becomes ambiguous.

The interoperability question centers on whether tmux's visual alert signals are properly propagated through nested or layered terminal environments, particularly when both layers attempt to handle bell events or screen modifications. There is uncertainty about which component ultimately renders the visual feedback and whether configuration conflicts arise from overlapping responsibilities.

Key options involved include visual-bell, visual-activity, and monitor-activity, which may interact differently depending on the terminal's own alert handling logic. The behavior of these settings in combination with external multiplexers or enhanced terminal features lacks clear documentation in many versions.

Does tmux's visual alert system integrate cleanly with terminal multiplexers that also implement bell handling, or do conflicting visual signals emerge? Should visual-bell be disabled when using a terminal that already processes bell events for visual feedback? What is the recommended configuration to ensure alerts are neither lost nor duplicated across the alert delivery chain?
