Title:
  UI freeze for up to 10sec when maximizing window

Status in Unity:
  Confirmed
Status in “nvidia-graphics-drivers” package in Ubuntu:
  Confirmed
Status in “unity” package in Ubuntu:
  Confirmed

Bug description:
  Maximizing a terminal window often takes up to 10 seconds on my
  system. During this time the mouse cursor can move but the UI is
  otherwise unresponsive.

  To reproduce:
  1) Launch a terminal window, e.g. via Ctrl-Alt-T
  2) Click the maximize button in the terminal window

  Expected results:
  Terminal window does fullscreen instantly

  Actual results:
  Terminal window stays at the original size for up to 10 seconds. During this time no UI elements work (can't switch to a new window, the launcher is unresponsive, etc). The terminal window is eventually drawn full-screen.

  This is reproducible about 75% of the time I try to maximize a
  terminal window. I haven't seen the problem affect windows in other
  applications. If maximizing a window does not produce the delay, un-
  maximizing it then re-maximizing it often causes the delay to appear.

  This is a recent regression - I believe the freeze/delay was not
  present in Unity 6.8.
