@abasba: What, exactly (describe it) are you calling "stock Amazon screensavers"?
Because that can only happen in very unlikely circumstances with a functional install.
Which makes me thinks you're either on an SO device, or something simple went wrong along the way
.
(FWIW, that images looks *nearly* perfectly fine, encoding-wise: it's 16 colors, which is good, and grayscale, which is good, but it's a tiny bit too efficiently encoded (i.e., 4bpp Gray channel, not 8bpp), which might upset something along the way. FWIW, it *is* the right way to do a 16 colors grayscale image, it's just not the most compatible where the Kindle is concerned
).
