--- Comment #20 from Andrew Simmons <agsimmo...@gmail.com> --- I've also been experiencing this issue with the default Translucency settings. Disabling the Translucency effect made my glitched window disappear. I've had this glitched window effect happen with at least Firefox, Chromium, Slack, and Dolphin (likely just because these are some of my highest use applications). It seems to happen every 1 to 2 days. I think it generally occurs when either dragging or maximizing (by dragging to the top of the screen) a window.
