Bug detailed description:
-------------------------
glean case depthStencil failed. This case seems is used to test
GL_EXT_PACKED_DEPTH_STENCIL extension.
I got this result on some machines like Q965, 945G, 945GM
depthStencilFAIL
Image returned by glReadPixels didn't match the expected result
(0xbf82ae60 != 0x0)
depthStencilFAIL
Image returned by glReadPixels didn't match the expected result
(0xbf82ae60 != 0x0)
depthStencil: PASS rgba8, win+pmap, id 88
glReadPixels GL_DEPTH_STENCIL rate: 0.00 MBytes per second.
glReadPixels GL_DEPTH/GLuint rate: 0.00 MBytes per second.
glReadPixels GL_DEPTH/GLushort rate: 0.00 MBytes per second.
But I failed to simply this issue as simple case. running the attached test
case(which mostly the same as glean case) can give me the correct result, but
not glean.
Reproduce steps:
----------------
1. start X
2. ./glean -r log -t depthStencil
Current result:
----------------
depthStencilFAIL
Image returned by glReadPixels didn't match the expected result
(0xbf82ae60 != 0x0)
depthStencilFAIL
Image returned by glReadPixels didn't match the expected result
(0xbf82ae60 != 0x0)
depthStencil: PASS rgba8, win+pmap, id 88
glReadPixels GL_DEPTH_STENCIL rate: 0.00 MBytes per second.
glReadPixels GL_DEPTH/GLuint rate: 0.00 MBytes per second.
glReadPixels GL_DEPTH/GLushort rate: 0.00 MBytes per second.
Expected result:
----------------
glean case depthStencil should pass
