If nothing is broken, there will be no fix. AWT and NEWT are free to have different expectations on vertical orientations. It's a matter of pixel or image coordinate system.

You can modify your texture coordinates or flip the pixels.

Why doesn't setMustFlipVertically​() work for you? If you use the high level API from the beginning to the end, it will work. If you create a Texture object but manage the binding by yourself, you'll be responsible for the flipping. getImageTexCoords() takes into account the value of getMustFlipVertically().

By the way, I advise you to use try-with-resources statements instead of calling close().
