The only thing I can think of is the copy code which copies/converts the GlyphInfo image-data into the stream submitted to X, in XRGlyphCacheEntry.writePixelData(). I guess the pixel-data I get from the GlyphInfo structure is the same, maybe access using Unsafe is somehow broken or shifted by a byte? For now I assume a fixed oder when uploading the glyph-data (didn't find any docs about it), could it be different on that machine?
