Hello, I apologize if this is the wrong place to comment, but just wanted to add I am seeing the same problem, except with an ATI driver, not intel. If it helps:
KDE 4.5.1 (latest as of writing) With desktop effects OFF: glxgears: 25,000 frames in 5 seconds fgl_glxgears: 4500 frames in 5 seconds (this is great!) With desktop effects ON (without blur) glxgears: 4,000 frames in 5 seconds fgl_glxgears: 1100 frames in 5 seconds With desktop effects ON (with blur) glxgears: 500 frames in 5 seconds fgl_glxgears: 200 frames in 5 seconds I have ATI Mobility Radeon HD 3650 Just a few days ago the driver was updated and reports as follows (from their Catalyst center) - 2d Driver version 8.72.11 - RandR version 1.3 Makes a huge difference with some apps -- e.g. Firefox 4 beta's new tab candy/panorama thing is incredibly slow and jumpy with desktop effects on. With desktop effects off, it is brilliantly smooth...
