VDC bitmap with 8x2 cells

I'm trying to set up the VDC screen to a 640x200 bitmap with 8x2 pixel
attribute cells. Char height is set to two, vertical display registers
are quadrupled. I get a screen, but the two rightmost columns display
flickering garbage. Changing the number of characters per line to 78
or less makes the bug go away. Does anyone know of a workaround?
