Hello,
The LINE_WIDTH() command sets the width of a line in 1/16 of a pixel increments. So using LINE_WIDTH(1) will set the line to 1/16 of a pixel wide. This is also the same with the VERTEX2F() command, it works on 1/16 of a pixel accuracy.
Also you've set the color of the lines to be black, which is also the background color for your display.
Try either selecting a different color for the background color, or line color and using VERTEX2II (or adjusting the values in VERTEX2F accordingly):
CLEAR_COLOR_RGB(255, 0, 0)
CLEAR(1,1,1)
COLOR_RGB(60,60,60)
CMD_FGCOLOR(0XFFFFFF)
CMD_BUTTON(56, 8, 208, 86, 28, OPT_FLAT, "208x86")
COLOR_RGB(0, 0, 0)
BEGIN(LINES)
VERTEX2II(55, 7, 0, 0)
VERTEX2II(55, 95, 0, 0)
VERTEX2II(265, 95, 0, 0)
VERTEX2II(55, 95, 0, 0)
VERTEX2II(265, 95, 0, 0)
VERTEX2II(265, 7, 0, 0)
VERTEX2II(55, 7, 0, 0)
VERTEX2II(265, 7, 0, 0)
END()
