The ext would also have to be enabled in the shader. Yes, I understand. But this would still leave radeonsi without required functionality. So making this bug about enabling GL_ARB_arrays_of_arrays for an application that (pretends*) to need it, seemed reasonable and more descriptive. * I've played about 30 minutes now with those environment variables set and haven't noticed any visual corruption on radeonsi which doesn't expose GL_ARB_arrays_of_arrays. So I'm not sure if the game actually *needs* the extension?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
