Terminal Integrated Bell visual flash behavior across operating systems

Visual Studio Code provides the Terminal > Integrated: Enable Bell setting to manage auditory and visual alerts when a bell character is received from the underlying shell. While disabling the auditory component reduces notification noise during long-running CLI processes, the resulting visual feedback is inconsistent.

The goal is to maintain a consistent visual cue for process completion without triggering system-wide audio alerts. However, the behavior of the visual bell flash varies depending on the operating system's window manager and the specific integration of the VS Code terminal.

• On Windows, the flash may behave differently than on macOS or Linux.
• The priority of these alerts can shift between stable releases and Insiders builds.

Does the visual flash behavior synchronize across all supported platforms when the auditory bell is disabled? Is there a configuration to standardize the visual alert independently of the OS window manager?
