This is possibly Windows 10/NVidia GTX -specific, don't see it happening on other OSes: STR: Visit http://clb.demon.fi/dump/webgl_color_buffer_readpixels/webgl_color_buffer_readpixels.html (or download http://clb.demon.fi/dump/webgl_color_buffer_readpixels/webgl_color_buffer_readpixels.zip) Observed: The WebGL context on the page reports the following states: GL_IMPLEMENTATION_COLOR_READ_TYPE for FBO 0: 0x1401 GL_IMPLEMENTATION_COLOR_READ_FORMAT for FBO 0: 0x80e1 where 0x1401 is GL_UNSIGNED_BYTE and 0x80e1 is GL_BGRA. However calling glReadPixels() with this type & format combo fails in an GL error.
