what's the problem with the sfml2.0 , i upgraded my game from 1.6 to 2.0 just to avoid the so called graphics bug, but then i met with the same problem--game run quite well on one machine, but appear in a flash on another, who said the bug is removed!!!
the problem is: i tried to load a big texture, only to get the annoying "internal size to high problem", almost the same problem i tried to load a big image in SFML1.6
