This was happening on gnome-shell, not unity. The report says unity I gather because the crashes got so bad I had to switch back.
I feel it might be tied up to the dynamic transparency stuff on either the top panel, or the dock. I opened another bug about the crashes here: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1735127 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1730460 Title: Framerate drops when moving windows across physical displays To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1730460/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
