In any case, all seems to work fine using mesa. Doing a git bisect to see when this problem got solved, I found this commit: commit 4acf71c89b5ef5e2fe8c1a3d7ecf6031e191463c Author: Kenneth Graunke <<a href="mailto:kenneth@whitecape.org">kenneth@whitecape.org</a>> Date: Mon Dec 28 14:20:28 2015 -0800 drirc: Disable ARB_blend_func_extended for Heaven 4.0/Valley 1.0. Unigine Heaven 4.0 and Valley 1.0 use dual color blending but don't specify which fragment shader output is which, so there's at best a 50/50 chance of us guessing it correctly. This is invalid. Unigine fixed this in 4.1 and 1.1 versions over a year and a half ago, but hasn't actually released them for whatever reason. So, add the workaround back so that it works for most people. Fixes Heaven 4.0/Valley 1.0 rendering on Ivybridge. For whatever reason, Broadwell worked. 4.1 and 1.1 have always worked.
