 ## [Unreleased]
 ### Changed
+- Malformed windows that are managed through rules should be eligible for window alpha, focus follows mouse, and window borders [#788](https://github.com/koekeishiya/yabai/issues/788)
 - Improve behaviour of *focus_follows_mouse autoraise*, preventing a window from being raised if it would occlude some other window. autoraise is temporarily disabled while a menu is opened. [#407](https://github.com/koekeishiya/yabai/issues/407)
 - Work around broken Apple code for retrieving menubar dimensions on Apple Silicon M1 [#793](https://github.com/koekeishiya/yabai/issues/793)
 - Rework query attributes and define dataformat as part of the API [#775](https://github.com/koekeishiya/yabai/issues/775)
