** Description changed:

  I first noticed this under wine, but have reproduced it with several
  Linux-native games including "Yo Frankie!" and "Cube 2".
  
  When shaders are disabled, I see normal performance. When shaders are
  enabled, however, I get very jerky performance; essentially one-two
  seconds of normal performance alternating with a freeze of at least 0.5
  second.
  
  This is a regression from Jaunty.
