Description Samuel Pitoiset 2011-06-17 06:18:33 UTC

Hello,

I have rendering problems when I try to display more then 65532 vertices with my Radeon X600.

I attached the apitrace file http://www.quickfilepost.com/done.do?get=4f69f193a4cd2ef1b5e8372a824317d2&tb=.

You can see the patch here http://paste.pocoo.org/show/410186/ and the screenshot here http://www.quickfilepost.com/done.do?get=72e61088b58f7fb7b11781a47381b3f6&tb=.

Thanks.
