[Bug 1064329] Re: High CPU load (above 50%) on Xorg process when browsing low graphic intensive sites
I can confirm this bug but I'll have to disagree with Karl. This problem seems to be unrelated to the DE in use as I am experiencing it on Openbox, LXDE and Unity. I can easily reproduce this bug by accessing any type of HTML5 website. Here are some examples: http://fff.cmiscm.com/#!/main http://sidigital.co/ http://www.whitehouse.gov/issues/preventing-gun-violence As for CPU load when moving around windows, the CPU usage does seem to be higher than necessary (~15% on LXDE at the specs outlined below). Is this how it's supposed to be? Some additional information: - reproducible both with FF and Chrome - mean CPU load on HTML5 website ~30% with Core i5 @ 2.66GHz - graphics: AMD HD5650 Mobility Radeon on FGLRX (Catalyst 12.6) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1064329 Title: High CPU load (above 50%) on Xorg process when browsing low graphic intensive sites To manage notifications about this bug go to: https://bugs.launchpad.net/chromium-browser/+bug/1064329/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1064329] Re: High CPU load (above 50%) on Xorg process when browsing low graphic intensive sites
I believe this is a problem that roots in unity, compiz and xorg working together. ANY application that continously updates the screen causes compiz AND xorg cpu usage to go up. Examples that trigger the problem include HTML5-animated-websites, moving around terminal windows with the mouse, the spectrum analyzer in audacious, and flash animations/videos. On my machine (Thinkpad t430 with Intel i7 3520M and Intel HD 4000 graphics) the cpu usage in Precise was already much too high: After a fresh boot open two terminals, start top in the one and keep moving around the other one. Xorg and compiz together use 10-20% cpu. In Quantal the same experiment results in 20-40% cpu usage. For nothing but moving a small window around. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1064329 Title: High CPU load (above 50%) on Xorg process when browsing low graphic intensive sites To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1064329/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
