Title:
  major slowdown in 3d games after a while

Status in compiz package in Ubuntu:
  New

Bug description:
  After upgrading to Vivid, I've been experiencing a new issue (wasn't
  present before in Utopic): after a period of let's say about a day,
  and multiple suspend-resume cycles in that period (> 5), some 3D games
  will have so low FPS as to become unplayable.

  (I've confirmed this with multiple games, like Massive Chalice, Space
  Run, Frozen Cortex, Trine, which used to work properly in Utopic.)

  I'm not sure the problem is with compiz, but I can make the problem go
  away by running "compiz --replace" in a terminal - Compiz will restart
  and my FPS goes back to normal.

  I'm using nVidia drivers 340.76, as can be seen from the submitted
  files.

  Is this a known issue? Should I try running some other driver version
  to see if that's the problem?

  Cheers
