["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Virgil Brummond, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily kernel folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11.1

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  Intel graphics performance regression in 2.6.32-19 lucid kernel update
  (was: Firefox Slows Down Compiz)

Status in The Linux Kernel:
  New
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Latest status on the bug report:

  I think this would be a kernel regression in 2.6.32-19 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. Not sure about -17 and
  -18, but probably at least -17 was right. More input and testing
  welcome.

  Possible: amd64 only? bryceh reported not having the problem.


  
  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.
