The 4056x3040 mode appears to need more vertical blanking lines than any other, leaving a black bar at the bottom of the image. Increase IMX477_VBLANK_MIN from 4 to 48 to compensate. (It may be possible to reduce it slightly further, but fix the regression for now). raspberrypi#7109 Signed-off-by: Dave Stevenson <[email protected]>
