From e8f48b1dc99a8db05c07d442acd3baf8f3620f6e Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Sun, 2 May 2010 17:37:18 +1000 Subject: [PATCH] softpipe: invalidate cache view when swizzles are different. Current code only invalidated if the texture was different, however we store swizzled values in the cache, so we need to invalidate in that case also.
