Increasing or decreasing the font size in the buffer also has no effect, I can't get a zero height or width. Disabling mode lines means you're working in the wrong direction. Frame resizing always tries to make windows at least one line high and two columns wide. You have to make a small window and make its mode lines tall. Then you have a chance to crash redisplay with macros like WINDOW_BOX_HEIGHT_NO_MODE_LINE and WINDOW_BOX_TEXT_HEIGHT that subtract mode line heights from a window's total height. martin
