Images in Qt show up incorrectly if each line is not aligned to 32 bits. It is pretty common for an image's lines to be 32-bit alinged by chance. Obviously any 32-bit image will not have any problem. For the bug to manifest itself you'd need... * a 1-bit image whose width is not a multiple of 32 * an 8-bit image who width is not a multiple of 4 Testing more images now and added a 7x13 png test image
