Hello! On Natty, if both “Window decorations” and “Blur” plugins are enabled, and the settings for blur include “Alpha blur”, the windows where alpha blur applies have messed up shadows. (I use “normal” as the window filter for alpha blur; examples of transparent areas are the gnome terminal in some profiles, and unfocused window title bars, and some popups.)
First of all, the shadowed areas are also blured, which I believe to be wrong behavior. (Only translucent part of “logical” windows should be blured, not effects like shadow.)
Second, the shadow becomes “messy”: it’s a dynamic bug, the exact effects vary when moving windows around, including darkening or lightening of the shadow, and various lines and areas of varying opacity. I’m including a screenshot with an example.
