  : I find a bug with jpeg show, If define FASTJPEG 0, then draw image
would be leak some points or draw some bad points, FASTJPEG =1 is 256 colors
,it's normal. I think and test decode jpeg is right, may be draw pixel occur
error, Any patch or suggestion can help me?

What format framebuffer are your running? If you're
running palette mode, then the decode could not match
your loaded palette. When FASTJPEG is set, then the
image decode always includes a palette, and it is
then reloaded when displayed. The same problem
may occur if you're running a low res mode, like 332
truecolor.

Explain a little more about the "leak", as well as your
hardware fb format.

Regards,

Greg
