Description Leslie Nooland 2010-08-30 23:37:01 UTC 
I am using the latest build of gnome-shell, and I get this pretty irritating delay for a while now. When in ZoomOut mode, when i hover over a window the shell will freeze for 1-2 seconds until the (X) thing shows up on the top right of it.

If I zoom in/zoom out without hovering the mouse over the workspaces there is no delay, so basically whats causing the delay is hovering the mouse over any window in any workspace until the (X) shows up. Also if I hover my mouse over empty workspaces no delay.

I am using it on Ubuntu Lucid, and I am using radeonhd. I want to mention that the ubuntu repository package does not present this issue.

the delay dissapeared with the latest build.
Comment 3 Leslie Nooland 2010-10-25 23:27:34 UTC 
the problem is back, it seems if i modify gnome-shell.css it will go away, and it did but now i am unable to do that anymore, as soon as i install a new css theme, mutter will go 99% CPU and my system will freeze,I need to kill mutter to regain control.
Comment 4 Leslie Nooland 2010-10-26 13:03:40 UTC 
the problem seems to be caused by these lines:


#message-tray {
    background-gradient-direction: vertical;
    background-gradient-start: rgba(0,0,0,0.01);
    background-gradient-end: rgba(0,0,0,0.95);
    height: 36px;
}

by replacing them with this:


#message-tray {
   background-color: rgba(0,0,0,0.4);
   height: 32px;
   -st-shadow: 0px 0px 0px 2px rgba(255,255,255,0.4);
}


i managed to remove that stuff.

i also noticed the lines are in .chat-send, chat-receive, etc, but i have not tested them yet.

the interesting part is it is not caused by the other similar (gradient) lines contained in many other parts of the file.

P.P.S. I removed: 

   -st-shadow: 0px 0px 0px 2px rgba(255,255,255,0.4);

it was not rendering right anyway, another bug.
