If you try drawing a gfx font text thats coloured and you have a blend < 255 then it corrupts the text...
For example...

-- load our graphic font
image = loadimage("nums.png")
font = loadgfxfont(image, "0123456789", 10)
count = 0
function onmainloop()
clear(0,2550,0)
blending(200)
-- draw counter
drawgfxtext(font, 10, 10, count, 255,0,0)
-- get text width and draw a number aligned to right
width = gfxtextwidth(font, 9)
drawgfxtext(font, screenwidth() - width , 200, 9)
-- get text width and draw a number aligned to center
width = gfxtextwidth(font, 69)
drawgfxtext(font, screenwidth()/2 - width/2 , 100, 69)
count = count + 1
end
function onstylusdown(x,y)
quit()
end
