Visual glitch of planet in stellaris

Stellaris is 32-bit only. This was tested on debian testing x86_64 with
compiled for 32-bit and installed git master radeonsi driver and libGL. 

I confirmed stellaris was using the correct libGL and radeonsi_dri via
/proc/pid/maps.

I compiled mesa with:

CC="gcc -m32" CXX="g++ -m32" ./autogen.sh --with-gallium-drivers=radeonsi
--with-egl-platforms=drm,x11 --enable-texture-float --enable-glx-tls
--enable-shared-glapi --enable-glx --enable-driglx-direct --enable-gles1
--enable-gles2 --build=x86_64-pc-linux-gnu --host=i686-pc-linux-gnu

        Run 'make' to build Mesa


My graphics card shows up as:

Advanced Micro Devices [AMD/ATI] Curacao XT [Radeon R7 370 / R9 270X/370 OEM]

I have attached a picture with this description. I don't see a way to add
multiple attachments so I will attach a picture of what it should look like as
well as the apitrace after I submit.

I'm new to all this so sorry if I missed anything! I have a vested interest in
fixing this and am a programmer(though super inexperienced with graphics) so
feel free to give me technical instructions.
