| Summary | JanusVR Browser rendering misses floors on radeonsi, works on intel |

Application download is here: http://janusvr.com/ I made a short apitrace (26 megabyte): http://haagch.frickel.club/janusvr.trace On intel Ivy Bridge it renders fine. On radeonsi the floor is missing. Using mesa git master with this patch: https://bugs.freedesktop.org/show_bug.cgi?id=80880#c10 on a HD 7970M.
What sort of problems does this cause? So is it only when using hardware accel?

floors missing on radeonsi
It seems to be a purely visual problem in the rendering. Here is a screenshot
with radeonsi.
I don't quite know what you mean with hardware accel. I just tried with
LIBGL_ALWAYS_SOFTWARE=1 janusvr, so llvmpipe. With llvmpipe the floors are also
missing like on radeonsi.
Maybe this was misplaced in the radeonsi component and happens in all llvm
using or on all gallium drivers?
Maybe the llvm version is relevant: 3.6svn 214915
Someone told me the shaders are a bit wonky and partly shouldn't work in the
first place, but on all proprietary drivers + intel on linux it seems to work,
so I don't know.

Could be an issue in st/mesa or other driver-independent Galli= um code then. Does glretrace also report a few OpenGL API errors like these on intel? 5946: message: major api error 1: GL_INVALID_OPERATION in Inside glBegin/gl= End 5947 @0 glTranslatef(x =3D 2.000085, y =3D 0, z =3D 0) 5947: warning: glGetError(glTranslatef) =3D GL_INVALID_OPERATION
