Ok, I replaced my jars with latest Jogl version and the problem still persists. Result: bar-left-rendered.png (don't mind the blue line, it's from another png).

When the texture is loaded as BufferedImage, it works fine. If I convert the texture to DDS format (with alpha channel) and load it via TextureIO, it also works fine.

This is wrong, I have just checked with The Gimp 2.8.4, your image has an alpha channel and the background is transparent.

The image is created in Photoshop and contains only 3 channels. No alpha channel. No idea why Gimp shows the alpha channel as existing.
