Thanks for the report! As per the spec, it appears that compressedTexSubImage2D does not support COMPRESSED_RGB_ETC1_WEBGL https://www.khronos.org/registry/webgl/extensions/WEBGL_compressed_texture_etc1/ > Compression format COMPRESSED_RGB_ETC1_WEBGL may be passed to the compressedTexImage2D entry point. > Revision 5, 2014/03/07 > Remove ability to use the format with compressedTexSubImage2D, as per the GLES extension spec. Closing this as invalid. If I've made a mistake, please reopen. Note, unexpectedly we don't return an error for the case. Bug 229182 tracks this omission. |
