Mesa version 17.3.3
AMD/ATI Barts PRO Radeon HD 6850
Detail in https://github.com/supertuxkart/stk-code/issues/3097, this bug cause
wrong animation in stk.
And i think 2.2 / 2.3 equation isn't causing this bug, because from what i see
zero is represented correctly in stk, also some amd devs told me barts switched
to use the new formula long time ago.
Any idea?
