When I updated to 11.10, I thought that any problems would be solved and all graphical glitches would be better. After upgrading, my whole system got borked, and everything looked ugly. I ended up fixing most everything, but for one thing.

The shadows for any application is ugly. It is hard to describe, so I hope the picture helps.

Notice the odd shadows. The shadows are all wierd

They also are common after closing a window or moving it to a different workspace

I know this is a small problem, but it still bugs me. Any fix for it?

  • It looks like those shadows are transparent through to your desktop. Nifty! Have you been messing around with Emerald or Compiz in 11.04 before upgrading? – Christopher Kyle Horton Oct 18 '11 at 21:12
  • Yes I did, but nothing with shadows – Stramato Oct 20 '11 at 1:18
  • I'd like to add that this issue seems to be related to transparent backgrounds (like in gnome-terminal) being vertically-mirrored. – ulidtko Oct 31 '11 at 13:04

I thik it's the 'Blur' effect in CompizConfig Settings Manager. A few days ago I tried to add blur to my transparent Menus and ended up in having this nice shadows (that reflect your Desktop but mirrored vertically). Try disabling the 'Blur' effect and see if the shadows disappear.

  • Which blur? motion blur or blur windows? – Stramato Oct 20 '11 at 1:22
  • I played around with blur for windows got that effect and by turning the window blur effect off I got rid of it. But now I'm unable to reproduce it...damn. I think at the moment Compiz has a lot of strange effects. – joschi Oct 20 '11 at 6:21

Oh boy. I'm sure there's a way to disable shadows somewhere, if I find out how I'll let you know. For a temporary fix, when you are logging in, click the cog icon next to your name and select Ubuntu 2D.
