[Bug 595845] Re: libcairo2 1.9.10 makes Ubuntu 10.10 slow
I also have this bug. Updated to 10.10 and had problem with X so am running novoeau due a problem with the legacy drivers for my old MX440 nvidia card. Tried the clearlooks theme and while it appeared to make a small improvement - you can see the progress bar actually moving, Xorg is running at 75% CPU utilization while the progress bar is in the building data structures phase. This occurs regardless of weather update manager is the visible window or not. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/595845 Title: libcairo2 1.9.10 makes Ubuntu 10.10 slow -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

IMO, they better postpone this release to wait for better drivers or even pass it completely.

I can also confirm this issue, not sure if libcairo is truly to blame, but this slowness was the first thing I noticed on my freshly installed 10.10 beta (fully updated). Quickly scrolling through lines of text in gnome-terminal is enough to cause X to completely consume 1 core on my Q6600 and the perceived user experience is really bad. 2.6.35-19 x86_64 nVidia GTX 460 with 256.53 driver -- libcairo2 1.9.10 makes Ubuntu 10.10 slow https://bugs.launchpad.net/bugs/595845 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I'm also experiencing these problems, and I'm speaking about high CPU usage due to xorg when scrolling in applications (eg. Firefox, terminator, pidgin and other).

I would say partly fixed. The time issue, e.g. for update manager to Building data structures, seems to be solved. The cpu load issue is still there: - Ambiance 80-90% - Clearlooks 1-2% for the Ontv test case I mentioned earlier.

is that specific to Ontv? I don't think so. Ontv is a means to me to compare the cpu load for different types of progress bars/themes. Was that an issue in lucid? or in maverick using cairo 1.8? Yes, comment #8 above confirms that the load issue is present in Lucid as well. do you get the same issue using other murrine themes?
