Hi there.
On some texture resolutions our application crash with enabled compressed textures and mipmap.
Happens only with AMD gpus. Tested on professional and game card with latest drivers.
Minimal code for reproduce. Sample texture attached to this topic.
GLuint texture = 0;
glGenTextures( 1, &texture );
glBindTexture( GL_TEXTURE_2D, texture );
glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR_MIPMAP_LINEAR );
glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR );
glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT );
glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT );
glTexImage2D( GL_TEXTURE_2D, 0, GL_COMPRESSED_RGB, w, h, 0, GL_RGB, GL_UNSIGNED_BYTE, data );
glGenerateMipmap( GL_TEXTURE_2D );
This feature very important for us. Hope for soon fix.
