Title:
High CPU load (above 50%) on Xorg process when browsing low graphic
intensive sites
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%.
