I have something similiar, but I'm not sure it is the same or not. Here's my case after upgrade from Feisty to Gutsy.
When I load netvibes in firefox and dragging the widget, it is showing very high cpu-usage (nearly 100%). This phenomenon happened when I was viewing large image using comix and dragging around. There's another case, which is when I open the screensaver but I'm not sure whether this is normal or not. Was performed fine in Feisty too. -- High cpu usage on Xorg with gnome-terminal and transparency https://bugs.launchpad.net/bugs/148138 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
