run ./bin/ext_framebuffer_multisample-accuracy 2 stencil_resolve -fbo -auto
output:
Pixels that should be unlit
  count = 126470
  Perfect output
Pixels that should be totally lit
  count = 131408
  RMS error = 0.708010
Pixels that should be partially lit
  count = 4266
  RMS error = 0.598696
The error threshold for this test is 0.400000
PIGLIT: {'result': 'fail' }

Reproduce steps:
----------------------------
1. xinit
2. ./bin/ext_framebuffer_multisample-accuracy 2 stencil_resolve -fbo -auto
Comment 1 Kenneth Graunke 2014-06-03 22:22:52 UTC 
Most of these tests seem to be fixed.  Now that there's a small set of failures, let's just open new bugs for specific test cases that fail.
Comment 2 lu hua 2014-06-06 06:34:53 UTC 
Verified.Fixed.
