From 021f15816e74ec012b8cb904d9f0bc05ff5885b0 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Mon, 23 Mar 2015 14:47:35 +0200 Subject: [PATCH] i830: Fix culling with user fbos on gen2 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Flip the cull bits when rendering to a user fbo on gen2. This was already done on gen3 (since before git history starts) but was missing from the gen2 code. Fixes rendering of the driver+kart model in supertuxkart kart selection screen.
