I managed to salvage 2.6.32-16 kernel from beta1 alternate amd64 CD. Using that kernel the problems seems to be away.
I cannot find 2.6.32-17 or 2.6.32-18 so cannot test those. I think that at least 2.6.32-17 was ok, at least, possibly -18 as well. I don't currently remember when I upgraded/rebooted to which kernel. ** Summary changed: - Intel graphics performance regression in recent lucid kernel update (was: Firefox Slows Down Compiz) + Intel graphics performance regression in 2.6.32-19 lucid kernel update (was: Firefox Slows Down Compiz) ** Description changed: Latest status on the bug report: I think this would be a kernel regression with intel performance. Even typing in Firefox feels sluggish. Appears both with lucid's 2.9 intel X.org driver and 2.11 from xorg-edgers. The problem is seen in sluggish behavior as soon as one or more applications like Firefox or Ubuntu Software Center are running. The application in use seems to be consuming close to 100% CPU when whatever even slightly graphical is done. + The problem was not there in 2.6.32-16 kernel. Original unmodified bug report: Binary package hint: compiz Desktop effects are noticeably slower while Firefox is open. My display adapter is an integrated Intel® Graphics Media Accelerator 4500M. I tested this using the built in Benchmark plug-in. When Firefox is not running I get a solid 60fps (vsync is enable I believe). Having a few GTK+ applications (such as nautilus, gedit.. etc) open does not slow the frame rate even when running the expo plug-in. Running Firefox causes a noticeable slowdown in the expo plug-in and desktop switching. The frame rate drops to 30fps and below and feels choppy. I have not modified the configuration of either compiz or my intel driver. I am running Lucid on AMD64. This occurs on both the Generic and the Preempt kernels.
