Adding to this (8.3.0 r7345), the issue is temporarily resolved by opening the Window:General>WindowColor color picker (no need to actually modify) or by modifying either Window:Automation>OnHoverOver or Window:Automation>NoInteraction sliders. Also interacts oddly with enabling/disabling the Window:Automation>AutoHide options.

Issue recurs when entering combat with or without any window automation enabled.
