Comment 19 for bug 88815

Timo,

Upon further investigation I think I may have found the real culprit - metacity.

As I had kdebase installed on my system, I decided to try "kwin --replace" within GNOME, and performance is back to normal! Maybe the problem is specific to metacity and not xorg at all (a reasonable hypothesis, as when I checked the feisty-changes list, metacity and xorg-server were updated within very soon of each other).

Anyone with KDE installed, try it out! Just make sure you go into kcontrol and in Desktop, Window Behavior, Moving, disable "Animate minimize and restore", then try kwin. Minimize and maximize some apps and hopefully you'll notice that it's instantaneous like before. Tested & verified on both my systems with nvidia, nv and i810 drivers.

In light of this, I'm reassigning/adding to metacity.
