Confirming this, happens on Radeon 8400 too.

--- Comment #2 from Vadim Girlin ptpzz@yandex.ru --- Created attachment 101111 --> https://bugs.freedesktop.org/attachment.cgi?id=101111&action=edit patch
It seems the game relies on specific behavior of inversesqrt, which is undefined when x <= 0 according to GLSL spec. The attached patch uses V_RSQ_CLAMP_F32 instead of V_RSQ_LEGACY_F32 for int_AMDGPU_rsq, this fixed the issue for me.

--- Comment #8 from tuxicoman debian@jesuislibre.net --- I have the same withe glitch on Civ5 shown on the CivV.png with AMD radeonsi open source driver. I don't have the problem with Intel open source drivers. I use Debian Jessie with mesa 10.2.6

Fix is there for upstream 10.2 but it only aplay if mesa is bulded against llvm 3.5, Debian Jessie version is currently builded against llvm-3.4.
So i think you can request that on Debian bugzilla.
