It can be irritating and distracting to have it showing while you’re trying to pay attention to something. The taskbar should hide when you’re watching a video, running a game, opening a document, or a website in fullscreen. It also shows which applications are currently open and running. It holds important features such as the Windows menu, the system clock, your volume manager, and network settings. Your taskbar is the strip going across the bottom of the screen by default. This bug has existed for a long time, dating back to Windows 7. The taskbar overlaying on top of games, YouTube videos, and web browsers such as Chrome and Firefox is a common issue in Windows.
