Comment 1 for bug 365260

I am also experiencing this issue, but I have ASUS X71A Notebook with Intel Mobile 4 integrated series. I have changed my window manager to Metacity and I get almost instant response, so it seems the bug is tied down to so Compiz. I have removed most of the extras in compiz-config and also applied rules to not include yakuake in running effects, but it didn't help. I guess compiz isn't happy with the high speed resizing motion of the dropping down yakuake.
