Just spotted this bit of news at Digit-life.com.
Andrew Vorobyew (anvakams), our video section editor, answering these forum questions related to screen flickering of NVIDIA GeForce FX 5900-based cards, informed that it seemed the reason of 2D flickering during scrolling of large and picture-rich texts was the 2D clock speed not reduced but set to the 3D nominal. The same flickering occurs in a number of menus or intermediate screens between tests (i.e. in 3DMark03). This problem was examined on 4 different graphics cards with different drivers. FX5800 doesn't produce such artefacts, but one of the old 5900 Ultra cards on different PCB caused the flickering as well.
Andrew believes the flickering is caused by a hardware GPU bug or PCB circuitry (repeated in the new design) that produces crosstalk and/or raises 2D clock.
