CyberVision64/3D Scratch lines on moved graphics Type of Failure: During graphical movement (e.g dragging a window) strange distortions appear beside the moved object. The distortions dissapear on steady displays. Cause: The pixel clock for the current screenmode has been choosen to high, therefore a conflict between the timing of the input/output of the video RAM may occur. Solution: Lower the pixel clock of the affected screenmode.
