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 Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1064329 Title: High CPU load (above 50%) on Xorg process when browsing low graphic intensive sites Status in Chromium Browser: New Status in “chromium-browser” package in Ubuntu: Confirmed Status in “xorg-server” package in Ubuntu: Invalid Bug description: While using grooveshark.com, I noticed a big bump in the Xorg process CPU usage after selecting its tab. It jumps from the usual >5% to more than 50%. The webpage is not graphical intensive, but the interface is all HTML5. I'm attaching a video that shows the effect. Note that the recording also adds some weight to the Xorg process, but it's still noticeable, from 20% to 50%.
