** Description changed:

  Using ppa:mir-team/qa-testing and ppa:mir-team/qa-testing2, eventually
  the frames you see get slightly out of order and slightly lagged.
  
  I've only ever seen this bug in ppa:mir-team/qa-testing and ppa:mir-team
  /qa-testing2 so there's a reasonable chance it's come from one of the
  branches being tested there, which are not on trunk yet.
  
  The issue seems more pronounced with bypass (qa-testing) but eventually
  appears using qa-testing2 as well (no bypass).
  
  It doesn't seem to happen when using a single monitor. Only with
  multiple monitors. But possibly haven't tested enough to be sure.
  
  TEST CASE:
  Open a terminal in XMir and hold down a key.
  Expected: Key appears to repeat smoothly.
  Observed: Key sometimes appears to skip one character/frame ahead, and then 
back again.
  
  WORKAROUND (1)
  1. sudo apt-get install compizconfig-settings-manager
  2. ccsm &
  3. CCSM > OpenGL > (untick everything except maybe "Sync To VBlank")
  
  WORKAROUND (2)
+ Use simpler single buffering desktop environment, like Xfce.
+ 
+ WORKAROUND (3)
  Unplug all external monitors. Use a single monitor :(
