    Can you please file a bug?
    Can you quantiify the slowness?
    i.e close all windows (expect one terminal window) and run
    gnome-shell-perf-helper --perf=core --perf-iters=3 and include the output in a bug please.

    Code:
    bash: gnome-shell-perf-helper: command not found...

    Err sorry correct command is:
    Code:
    gnome-shell-perf-tool --perf=core --perf-iters=3 --replace > output.txt
    BTW, I have just tested on GM45 here (OpenGL renderer string: Mesa DRI Mobile Intel® GM45 Express Chipset), does not seem to be slow at all, results:

    BTW, I have just tested on GM45 here (OpenGL renderer string: Mesa DRI Mobile Intel® GM45 Express Chipset), does not seem to be slow at all, results:
    I can't post the output file. After all of the windows stop dancing around the system hanged (in the activities view, without any windows nor icons). Mouse pointer was live but I couldn't click anything. The system didn't even respond to power button which always nicely send a shutdown signal to fedora. This time I had to long-press the power button to shut the system down.

    I'm all for filing the bug report. Is there another way to obtain the output file on Live beta?

    I sustain what I said before. Some animations are clunky but ONLY in the Activities in/out animations. Interestingly, during the automatic test transparent windows had smoother animations most of the time, with the same number of windows.

    The whole thing doesn't look like a performance problem but rather... like the activities in/out animation has been hardcoded to cover the animation in X steps of window movement, so the more distance is to cover, the clunkier the animation looks like.

    Also the Activities triggering seems off. Works with at least a 0.25 sec delay, while it's almost instant in F18.

    Once I get the output of the automatic test I'll post the bug report along with video recordings.

    I tried to point the tool to save the output file on my hard drive. The system hanged again after the test (or during the test?), as expected, but there were no output file in the location I specified, once I rebooted.

    Try doing a VT switch (ctrl-alt-f2), log in as root (no password required) and do killall Xorg then go back to VT1 (Ctrl-Alt-F1), you should see the login screen. Now select live user and you should be back in he session with the file in your home directory.

    Here's the output file.

    The results look OK, the animations don't. I'll post the videos.

    Videos added. Since I'm bombarding the topic anyway - can someone, please, tell me how to EDIT a bug description on bugzilla? :/
