[Bug 1004251] Re: Animations aren't smooth when sync to vblank is enabled

 

** Description changed:

- WORKAROUND:
+ WORKAROUND (PREFERRED):
  1. Run ccsm
  2. Go to Workarounds
  3. Enable "Force full screen redraws (buffer swap) on repaint"
+ 
+ WORKAROUND (RELIABLE):
+ 1. Run ccsm
+ 2. Go to OpenGL
+ 3. Disable "Sync To VBlank"
  
  ORIGINAL DESCRIPTION:
  When "Sync to Vblank" is enabled in the OpenGL section of the CompizConfig Settings Manager (the default setting for precise) animations, specially minimize and maximize animations, aren't smooth and stutter a lot. Moving windows, or entering the Expo mode are smooth though.
  
  Disabling "Sync to Vblank" CompizConfig Settings Manager  solves the
  problem. However, glxgears still informs that it is "running
  synchronized to the vertical refresh" so I am not sure what the "Sync to
  Vblank" options actually does.
