 377      * Tests show that the content of the back buffer after a discard flip is indeed not
 378      * reliable, so no game can depend on the exact content. However, it resembles the
 379      * old contents in some way, for example by showing fragments at other locations. In
 380      * general, the color theme is still intact. So Max payne, which draws rather dark scenes
 381      * gets a dark background image. If we clear it with a bright ugly color, the game's
 382      * bug shows up much more than it does on Windows, and the players see single pixels
 383      * with wrong colors.
