git-bisect? sysprof? INTEL_DEBUG=fall? haihao has got the reason of this issue, so I reassign it to him. fixed in mesa. commit cb453244caa15342bf229ee5ae16a78d038b8bdc Author: Xiang, Haihao <haihao.xiang@intel.com> Date: Thu Dec 18 12:57:41 2008 +0800 i915: check WRAP_T instead of WRAP_R for cube map texture. Note apps those don't use CLAMP_TO_EDGE/CLAMP for cube map texture have to suffer from fallbacks. verified against: intel-2008-q4 branch commit f96baeaac3ef41260ac3975750627ece073fdce0 master commit cb453244caa15342bf229ee5ae16a78d038b8bdc |
