--- Comment #2 from Christoph Haag haagch@frickel.club --- Created attachment 104183 --> https://bugs.freedesktop.org/attachment.cgi?id=104183&action=edit 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.
