Comment 42 for bug 38131

I have same kind of problem with Opera and Konqueror. Firefox also, but it makes Xorg return back to normal CPU usage much faster. For example Fluxubuntu page (www.fluxubuntu.org) makes my Xorg use CPU 100%. It doesn't matter which browser I use (at least if it is Opera, Konqueror or Firefox). I am using driver "nv".
