XCOM: Enemy Unknown Screenshot 1
Hair on certain characters in XCOM: Enemy Unknown does not look correct. See
the attached screenshots. This occurs on both Mesa 10.1.3 + LLVM 3.4 and Mesa
git + LLVM 3.4.2 via Oibaf PPA, Ubuntu 14.04.

Created attachment 103534 [details] Another variant of incorrectly rendered hair I'm seeing the same with radeonsi on a Hawaii. As you can see from the attached image, it looks a bit different from what the initial reporter saw. The stack I'm using is: GPU: Hawaii PRO [Radeon R9 290] (ChipID = 0x67b1) Linux: Git:~agdf5/linux:drm-next-3.17-wip (calls itself 3.16-rc4?) libdrm: Git:master/libdrm-2.4.55 + patch from http://lists.freedesktop.org/archives/dri-devel/2014-July/064743.html LLVM: 3.5 RC1 libclc: Git:master/0ec7437d9c Mesa: Git:master/74e100affc + some patches from Marek to fix Hawaii ("radeonsi: fix CMASK and HTILE calculations for Hawaii"; "gallium/util: add a helper for calculating primitive count from vertex count"; "radeonsi: fix a hang with instancing on Hawaii"; "radeonsi: fix a hang with streamout on Hawaii"; "winsys/radeon: fix vram_size overflow with Hawaii"; "radeonsi: fix occlusion queries on Hawaii"; "r600g, radeonsi: switch all occurences of array_size to util_max_layer") and can be found on mesa-dev. DDX: 1:7.4.0-2 + Patch from http://people.freedesktop.org/~agd5f/0001-radeon-enable-hawaii-accel-conditionally.patch X: 2:1.16.0-1 (1.16.0)

I think this may be due to missing GL_ARB_tessellation_shader extension. Mesa lists this as Status "started" but no driver implementation yet. I'll try to evaluate the status of this and see if I can verify that its indeed this missing extension. (That would also mean that XCOM is in fact OpenGL)
OpenGL 4.0... Why can't I edit even my own comments!?
I just tried the game with an Intel GPU and Mesa: Hair rendering is correct. So this is in fact something broken in radeonsi.
With llvm SVN Rev 225358 and mesa from git ge28f9d0 as of today hair is rendered correctly on R270X :) Can anyone of the other reporters confirm this?

The hair in L4D2 looks fine as well now, so let's assume this = is fixed.
