I installed gnome-shell - for who knows what reason - on Natty, from gnome3 launchpad PPA:

sudo add-apt-repository ppa:gnome3-team/gnome3

sudo apt-get update

sudo apt-get upgrade

sudo apt-get install gnome-shell

sudo apt-get install gnome-session

After I realized I made mistake:

ppa-purge ppa:gnome3-team/gnome3

sudo apt-get update

and reverted system to previous state. Everything seems fine except one problem - vertical spacing on some gtk elements. I had screenshot taken week ago and made new one for comparison (left window is good and right is bad):

Screenshot is from scite editor, but it's same in other editors, in Eclipse, in Nautilus side pane... Everything is condensed and in some cases (Firefox 10 dropdown addressbar history) bottom part of font is missing because of this issue.

Changing theme doesn't help, so it's not some gtkrc issue. If I use spartan non GTK+ theme there is not issue, in case it matters

Can I do something to solve this issue?

Update 1:

I launched Guest Session, and there were no issues, so problem is in my own profile.

I deleted ~/.compiz folder, but nothing changed after relogin

Following the link provided by Amith, I did:

gconftool --shutdown

killall -r -I -9 dconf

killall -r -I -9 gconf

mv gconf-backup .gconf

mv config-dconf .config/dconf

sudo reboot

Still nothing :(

What else could it be?

Update 2:

I managed to make Nautilus side pane as before, by hand crafting current theme's gtkrc file:

GtkTreeView::vertical_separator = 2

Now if someone could only provide tip how to set vertical separator for editors gtk widgets (whatever they are called). I could not find any reference

Also I found out that root user doesn't have this problem, as can be seen from this screen-shot:

In case someone gets other idea ;)
