This tutorial will show you how to turn on or off using acrylic material in the tab row of Windows Terminal for your account in Windows 10 and Windows 11.
Windows Terminal is a modern host application for the command-line shells you already love, like Command Prompt, PowerShell, and bash (via Windows Subsystem for Linux (WSL)). Its main features include multiple tabs, panes, Unicode and UTF-8 character support, a GPU accelerated text rendering engine, and the ability to create your own themes and customize text, colors, backgrounds, and shortcuts.
When you turn on "Use acrylic material in the tab row", the tab row in Windows Terminal is given an acrylic background at 50% opacity.
When you turn off (default) "Use acrylic material in the tab row", the tab row in Windows Terminal will be opaque.
