When on http://tech.mevio.com/ it's active scrolling that gets Xorg to use lots of CPU. But I'm not sure if it's related to firefox alone. I think I have observed the same behaviour with thunderbird. So it's more like Mozilla's framework and Xorg that aren't playing nice with each other. -- Firefox causes massive Xorg CPU usage https://bugs.launchpad.net/bugs/38131 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
