<p>I found that a new version of the nvidia driver was released a few weeks back and am testing that out - 260.19.12. It seems to support additional GLX extensions so I am hoping it behaves better with KDE.</p>

<div><br />My VGA card is an Intel Q45 SVGA controller. I opted to upgrade to KDE 4.5.3, but I still have the same problem. When I open Kontact, Kmail, Kaddressbook, Knode, Kmail, Xorg consumes 90%+ of the CPU and the remaining 9-10% is taken by the application.<br /><br />To add to it, since I have an extended desktop, my windows tend to take on an overlay of other windows: for example, If I have Firefox and Dolphin open, when I switch to firefox from Dolphin, then firefox has the contents of dolphin overlaying it. If I move the mouse around, I can see my web page, but it quickly gets overlay by the other open windows. Moving the window from one desktop and back sorts it out but just for a while...<br /><br />If I suspend compositing, all is well. I can work with all applications, including Kontact with no problem.<br /><br />Any pointers on this?<br /><br /></div>

<p>Mike,</p>
<p>Two things I found that helped for me in the NVIDIA world are:</p>
<p>1) Disable the BLUR effect.</p>
<p>2) Choose a different window decoration other than Oxygen.</p>
<p>The other random thing I found was that KNEMO is a CPU killer but that doesn't sound like what you are seeing.</p>
