Title:
  Waking from Sleep Makes Some Games Perform Sluggishly

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Upon waking my computer from sleeping, certain games will perform less
  responsively than before putting the computer to sleep. To be more
  descriptive, the games' visuals will appear to lag slightly
  (milliseconds) behind my input from the keyboard and mouse.

  This occurs most pronouncedly with the game Awesomenauts, while
  slightly improving in certain parts of the level (perhaps less CPU-
  intensive areas). The problem occurs, albeit less pronouncedly, with
  other games such as Counter-Strike: Source and Left 4 Dead 2 (if not
  all of Valve's Source games), Beat Hazard, and perhaps other games in
  my Steam library I have yet to try.

  Restarting the computer rectifies the problem, and renders the games
  snappy and responsive once again.

  It is unclear whether the games themselves become less responsive
  (CPU-wise), or whether it is the result of another link in the chain
  (input, GPU, RAM, HDD).
