           Summary: [bisected] [llvm] Blue color shift on videos in MPV
                    when using vo=opengl[-hq]
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW

Hi all,

After LLVM commit e88fc4046f70131e67411cee503201e3e9665891  [AMDGPU] SDWA: add
support for GFX9 in peephole pass, MPV videos have their colors shifted
significantly into the blue range. It is resolved with the commit directly
before the above. I am using an RX 480 on kernel 4.11.6, mesa git, xserver git,
and llvm git. Using other mpv outputs, such as vo=vaapi,vdpau,x11 or xv all
have normal video.

Let me know if you need any more information.

Thanks,
Sarnex
