            Bug ID: 82253
          Assignee: dri-devel@lists.freedesktop.org
           Summary: JanusVR Browser rendering misses floors on radeonsi,
                    works on intel
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: haagch@frickel.club
          Hardware: Other
            Status: NEW
           Version: git
         Component: Drivers/Gallium/radeonsi
           Product: Mesa

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:

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 Gallium 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/glEnd
5947 @0 glTranslatef(x = 2.000085, y = 0, z = 0)
5947: warning: glGetError(glTranslatef) = GL_INVALID_OPERATION
