Seems to be bug https://bugs.kde.org/show_bug.cgi?id=343803.
The bug seems to be triggered by the combination of Qt, plasma 5 *and* the legacy nvidia 340 driver. It is unfortunate that KDE people are marking this as "resolve" when clearly it is not. It is also unfortunate that they mark it as "upstream" (indicating that it is a bug in the nvidia stack) which suggests that they intend to do nothing about it, when in fact: - it is unclear if the bug was actually fixed with more modern nvidia proprietary drivers. The bug may be caused by some race and it may be merely the different timings in the more modern nvidia drivers or in noveau avoid triggering it; - it should be totally possible to have a Qt terminal that does not cause the problem, as Qterminal shows. ** Bug watch added: KDE Bug Tracking System #343803 https://bugs.kde.org/show_bug.cgi?id=343803 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1634565 Title: konsole badly broken in yakkety: crashes, leaves process behind on exit using 100% cpu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/konsole/+bug/1634565/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
