            Bug ID: 93566
           Summary: Shadow of Mordor is fading to white with Intel Mesa
                    driver
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i965
          Assignee: idr at freedesktop.org
          Reporter: d.spitznagel at goodbytez.de

Hello devs,

today I was testing Shadow of Mordor on my Intel Iris pro since tessellation
landed for gen7+ some days ago in master git.

Mesa:
glxinfo | grep OpenGL
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Haswell Desktop 
OpenGL core profile version string: 3.3 (Core Profile) Mesa 11.2.0-devel
(git-28dea26)
OpenGL core profile shading language version string: 3.30
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 11.2.0-devel (git-28dea26)
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 11.2.0-devel (git-28dea26)
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00
OpenGL ES profile extensions:

Steam start options:
MESA_GL_VERSION_OVERRIDE=4.3 MESA_GLSL_VERSION_OVERRIDE=430 %command%

When the main menu comes up, the complete rendered background (not menu
dialogs) is fading slowly to white (also ingame and benchmark).

If i append MESA_EXTENSION_OVERRIDE=-GL_ARB_compute_shader to my steam start
option, there is no fading > the menu is rendered as expected.

I have made an apitrace and replayed it...
Without GL_ARB_compute_shader there are errors, because Shadow of Mordor wants
to use it, but rendering LOOKS ok.
With GL_ARB_compute_shader the errors are gone, but there is this white fading.

So I guess there is something wrong with GL_ARB_compute_shader!
Could someone look into this?

You can download my apitrace here...

Kind regards
