I like to have my Gnome panel (the one with icons and the Ubuntu menu) on the right side, rather than making my wide-screen even smaller in height.
It worked perfectly except with the "Ambiance" theme, which recently became Ubuntu's default theme:
As you can see, the shadow is repeated vertically, which makes an awful impression of tiles. Other problem, shadows are printed horizontally even though the text is vertical, you can see "14" ad "Fri" shadows in dark behind the vertical text.
Is it a known bug? If not, how to fix it?
