- glDrawArrays always generate a glError::GL_INVALID_ENUM but draw properly. Replacing the glDrawArrays call with glDrawElements (passing the indice array) doesn't generate a GL_INVALID_ENUM.

- GL_TEXTURE_MAX_ANISOTROPY_EXT generate a glError::GL_INVALID_VALUE even if GL_EXT_texture_filter_anisotropic is present and  GL_MAX_TEXTURE_MAX_ANISOTROPY_EXT return a positive value, and the texture is mipmapped.
 
[edit]
 
- glDepthRangef generate GL_INVALID_OPERATION, even if the default 0.0f, 1.0f value is pass.
 
- glClearDepthf generate GL_INVALID_OPERATION, even if the default value 1.0f is pass.
 
[edit]
 
- 16bits (RGB565, RGB4444, RGB5551) NPOT textures display artifacts, same textures (in RGB or RGBA) display properly.
 
ps: Only affect textures created with glTexImage, FBO NPOT 16bits textures attachment are fine.
