Thread: Window corner bug

hi

want report bug, don't know report it. (metacity, compiz,...)
(i run regular date version of ubuntu in ubuntu classic mode)

problem: window corners round, there little bit of transparency in corner. establish transparency effect, metacity (i guess) shows wallpaper in transparent part of corner. gnome panel (when on top) drops shadow on top of wallpaper , because there no real transparency shadow isn't shown in window corner. result can see contrast between window corner , wallpaper.

know report bug? or there solution?
