Is it an application related issue then?

The specific line where Linthesia maps its textures onto GL could be found
here:

https://github.com/linthesia/linthesia/blob/master/src/Tga.cpp#L217

I tried changing it from RGBA to BGRA today, which did change the color output,
but still in incorrect colors like yellow and brown (or maybe I have completely
butchered my RGB translation "knowledge").

Is it a Quad? I believe they are pretty cheap these days...
