That change has caused a small problem with interlaced modes. It seems there you blank the last two rows. With text overscan set to maximum (241 lines for NTSC), while a non-interlaced Workbench screen is fine, an interlaced one is missing the bottom row of pixels (black shadow line of the Workbench window is missing at the bottom of the screen).
