It seems to be a bug in NVIDIA graphics adapter drivers which should be resolved in the GeForce 306.23 Driver. However you can also easily workaround the bug following the steps:

  1. Start NVIDIA Control Panel,
  2. Go to 3D Settings | Manage 3D Settings,
  3. Choose 'Integrated Graphics' for 'Preferred graphics processor' option,
  4. Apply,
  5. Install VisualSVN Server.
