Public bug reported: Both VMs that I upgraded to Xenial experience constant high cpu usage, and top reports compiz is by far the high user of cpu.
The high cpu usage is more apparent from outside the machine, were host reports guests are using close (or over at times) to 200% cpu, than in the guests which are reporting 60-100% cpu (multicore VM) for compiz, constantly. The VMs are using the QXL video driver and are using a spice channel for virt-manager / virt-viewer. ** Affects: compiz (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/1571918 Title: Constant high cpu usage in xenial under qxl/spice To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1571918/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
