On my original system where I found this bug, the behaviour was still consistent with Vimium.
However, I did recenty a fresh install of Lubuntu 13.10 and update to latest version of Chromium in the repos, and installed Vimium and on that machine (with a cheaper CPU) I do not have any high CPU usage there. My original system where I see this behaviour has been updated in place over the last 3 Ubuntu updates, so I suspected it could be indeed a problem with Chromium either of some libraries or more likely of home folder config settings from previous versions. To prove that, I renamed my ~/.config/chromium to ~/.config/-chromium in the problematic machine and started chromium with fresh settings (my ~/chache in tmpfs, so that is cleaned on everz shutdown). I installed Vimium and I browsed to several pages and I canot reproduce any more the behaviour. So in my case it seems Chromium has problems with older version settings or data in ~/.config/chromium. Removing that folder (backup it) solved the problem for me. I have to copy over my bookmarks from the older folder (lets hope the problem is not related to the number of bookmarks :) and take over manually the rest of the settings. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1261105 Title: chromium-browser 31.0.1650.63 high cpu on any page To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1261105/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
