Public bug reported: I have recently upgraded to KDE 4.7.4 from the PPA to get rid of constant crashes of the Desktop. Since then, some of the applications I extensively use throughout the day start to become extremely slow at some point after some hours of use (it is more the GUI that seems to be slow), use 100% CPU and if done quickly, they can be closed, otherwise they completely freeze within about a minute and keep on using 100% CPU. At least sometimes it is actually an X.org process that uses 100% CPU, not the actual application process.
I have this with Eclipse which I use most, but have seen the exact same behaviour also with GIMP and Firefox. The problem did not occur before the upgrade to KDE 4.7.4, but it is still just a guess that it has something to do with that. The same behaviour shows on two different PCs with a clean installation of Kubuntu 11.10 and KDE 4.7.4 from the PPA. ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/922022 Title: Applications freeze after several hours of extensive use To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/922022/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
