Oh I think I see why 3v1n0 changed the status. The graphical bugs described in Bug Description are mostly fixed now. However I think we need to ignore those. The fact remains that Unity should not be painting its own shadows. It should be leaving it up to the compiz decor plugin.
** Description changed: - As seen in the attached screenshot, the panel shadow in Unity (both in - 11.04 and 11.10) is drawn by simply overlaying it on the desktop - background. This causes a bit of ugliness when switching desktops (see - the thumbnails in the desktop switcher in the screenshot where one can - see a dark line at the top of each desktop), or when toggling expo - (there is no panel shadow), and is a bit of a "cheap trick" [with all - due respect :)]. + Unity paints its own panel shadow independently of the regular window + shadows. This is a redundant hack and should be avoided in future. + + Until 13.04, this caused several rendering bugs with respect to other + Compiz plugins. However most of those rendering bugs (described below) + have now been fixed under separate bug IDs. But the shadow is still + "faked" by Unity. Hence this bug. + + ORIGINAL DESCRIPTION: + As seen in the attached screenshot, the panel shadow in Unity (both in 11.04 and 11.10) is drawn by simply overlaying it on the desktop background.
