For info : the bug has been noticed on a computer featuring Windows XP pro sp2 and a nVidia 8600 GT 256 Mb graphic card.

It displays parasites on the screen (short horizontal lines appearing a disappearing quickly during the game).

The bug can appear after 1 or 2 minutes and continues under Windows, even if you close the game. You may have to restart the system to get rid of these lines.


To solve this problem, modify the "C:\Program Files\WorldOfGoo\properties\config.txt" file. In fact you just have to change the refreshrate value from 60 to 50.
