It is not a LibTiff problem. Without looking at your code (and likely we 
don't want to if it's too large or messy), they're really is no way of 
telling what the problem might be.

However, on Windows, results depending on display settings, usually point to 
the use of DDB (device dependent bitmap) where you ought to be using DIB 
(device independent bitmap) instead.
