Bug Description

Not much to say here. I can clearly see that during Superkey+W (unity shortcut) or Ctrl+Shift+E in Firefox animations on Intel are smoother. Some time ago I quit using AMD on my system because browser performance was unbearable - see http://askubuntu.com/questions/92080/why-do-i-have-poor-video-performance-in-browsers-with-a-ati-hd3650-gpu for details (video + overall experience).

In 12.04 the difference was much more severe. In 12.10 the difference is less pronounced (Firefox performance on AMD got better), but it's still noticeable (12.10, desktop perf.: Intel vs AMD).

I acquired *.apport files from different configurations on my system, so let me know what's needed to move the troubleshooting further.

The bug report is too vague, closing. Besides you're using fglrx, which we can't change other than push newer upstream versions.
