It seems, to me, that this bug was related with nvidia drivers. I was - finally - able to update nvidia to version 260.19.26 and this Kile performance problem disappear, cf. https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics- drivers/+bug/657634/comments/33
Kile: 2.1.0~svn1112278beta4-2ubuntu1 Nvidia: 260.19.26 (from ppa:ubuntu-x-swat repository) I would say that this bug should be reopen only if the problem remains with other X drivers. ** Changed in: kile (Ubuntu) Status: Confirmed => Fix Committed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/361843 Title: Kile 2.1 LaTeX editor is extremely slow -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
