System Environment: -------------------------- Mesa: (master)009ac0618ccb8c1347c353b576442ed70592c20e Bug detailed description: ------------------------- When use FBO for test with pointcoord will cause rendering reversed in vertical direction. Attached a test case to reproduce it. Reproduce steps: ------------------------- 1. xinit 2. run test case gl-pointcoord
Created attachment 55367 [details] test case for rendering FBO with point coordinate
Fixed by the following commit in master: commit eaf360e5bffc5630789367020252cd12fe586177 Author: Yuanhan Liu <yuanhan.liu@linux.intel.com> Date: Fri Jan 20 07:48:52 2012 +0800 i965: fix inverted point sprite origin when rendering to FBO When rendering to FBO, rendering is inverted. At the same time, we would also make sure the point sprite origin is inverted. Or, we will get an inverted result correspoinding to rendering to the default winsys FBO. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=44613 NOTE: This is a candidate for stable release branches. v2: add the simliar logic to ivb, too (comments from Ian) simplify the logic operation (comments from Brian) v3: pick a better comment from Eric use != for the logic instead of ^ (comments from Ian) Signed-off-by: Yuanhan Liu <yuanhan.liu@linux.intel.com> Reviewed-by: Ian Romanick <ian.d.romanick@intel.com> Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
It worked well on SandyBridge now. Verified. But it still fail on Ironlake and Pineview platform, but these are different things. I will open new bugs for them.
