There is no such restriction in neither ARB_texture_compression nor EXT_texture_compression_s3tc. This restriction only applies to [Compressed]TexSubImage calls not the [Compressed]TexImage calls. Among others certainly because otherwise non-square mipmaps would always fail at some point. So I believe the right fix would be to simply drop that test (but don't drop it from the subimage paths) - silently rounding up should not be necessary, things like expectedSize calculations should do the right thing already.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
