There is a bug within the DDS loader for the Texture resource. When a non-square texture is used (something like 1024x512 will do it), during mipmap loading, the smaller dimension will be reduced to 0, causing OpenGL to throw an INVALID_OPERATION error. Below I have a small fix that prevents this problem.

In egTextures.cpp, line 326 replace:

Code:

pixels += mipSize;
width >>= 1;
height >>= 1;

with:

Code:

pixels += mipSize;
width >>= 1;
if(width < 1) width = 1;
height >>= 1;
if(height < 1) height = 1;
