Subject: fix mixed conventional / generic vertex arrays which caused a wrong array order leadi... 
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=21cf414489af84b8bb374f76c36db8f0f1919733;p=mesa.git

fix mixed conventional / generic vertex arrays which caused a wrong array order leading to very bogus rendering (for instance WoW intro screen mentioned in #8250).
