XMir 1.0 (the old Xorg extension) is now deprecated and is not being
maintained or fixed. It is replaced by the new 'Xmir' binary (package
'xmir') introduced in Ubuntu 15.10 wily.

** Changed in: xorg-server (Ubuntu)
       Status: Confirmed => Won't Fix

Title:
  Multimonitor performance is quite slow and stutters with XMir

Status in xorg-server package in Ubuntu:
  Won't Fix

Bug description:
  Multimonitor performance is quite slow stutters with XMir. This does
  not happen with legacy X or native Mir; both of those are perfectly
  smooth. It's only XMir that's slow with multiple monitors.

  I suspect this is related to XMir's remaining buffer copies... ?
