It’s 16.10/GNOME/Wayland, did not happen in 16.04 I was previously on 16.10 KDE/X where it does not happen either. When Wayland is used, certain actions halts i915 and the cpu.
When GNOME 3.20 was in staging, LibreOffice was so bad it could not be used. Now it only halts when a Libreoffice window is dragged across the hidpi display. If that isn't done, the system does not halt. It is practically certain to be an i915 dri problem It may be related to GtkStyleContext and having multiple displays both low dpi and hidpi These two applications, when in gtk3, do something that halts in i915 One could fix the bug in i915 or make LibreOffice not do whatever it is that causes the halt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1647084 Title: i915 multiple display halt system when moving windows To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1647084/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
