As a game developer I can confirm that not only is your description of what constitutes a glitch accurate, we use it that way in game development as well. I'm a graphics programmer who previously used to work with UI and we often use the word glitch to refer to animation hiccups, graphics issues due to corrupted render buffers, etc. In the Need For Speed games from Ghost, we had a visual effect of disturbances running across the screen which was shown when you were hit by an EMP or seriously damaged[0]. We sometimes referred to that visual effect internally as the "glitch shader". edit: look at the UI elements: speedometer, mini map, etc. [0] https://youtu.be/qE4fgixKLpE?t=387 https://youtu.be/qE4fgixKLpE?t=387
