Firefox using 100% of CUP is occurring on my system as well. I have Desktop Effects turned on. I am using the latest build of Gutsy. This bug is more pronounced under the user account that has permission to change the system. Also, this bug appears on only certain web pages like gmail and igoogle. I have run Firefox without extensions and the problem still occurs.
Interestingly, I have noticed high CPU utilization by Firefox on my Windows Vista build. This leads me to think it is a problem with Firefox. -- firefox and xgl cause 100% CPU https://bugs.launchpad.net/bugs/145696 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
