We've seen the same issue here with our latest VMware driver which includes the LLVM version in the GL_RENDERER string. Sinclair found this code in the Unity shell in plugins/unityshell/src/unityshell.cpp: //In case of software rendering then enable lowgfx mode. std::string renderer = ANSI_TO_TCHAR(NUX_REINTERPRET_CAST(const char *, glGetString(GL_RENDERER))); if (renderer.find("Software Rasterizer") != std::string::npos || renderer.find("Mesa X11") != std::string::npos || renderer.find("LLVM") != std::string::npos || renderer.find("on softpipe") != std::string::npos || (getenv("UNITY_LOW_GFX_MODE") != NULL && atoi(getenv("UNITY_LOW_GFX_MODE")) == 1) || optionGetLowGraphicsMode()) { unity_settings_.SetLowGfxMode(true); } It looks like Marek added code in the r600 driver to include LLVM version info in the renderer string too: commit a3723fb9e32ab114dcffcf74946def92647c5f03 Author: Marek Olšák <<a href="mailto:marek.olsak@amd.com">marek.olsak@amd.com</a>> Date: Mon Jul 20 00:15:59 2015 +0200 gallium/radeon: add DRM and LLVM version to the renderer string So, if the reporter of this bug is using the r600 driver, that could explain things. He mentions a change in June/July. Clearly, the unity code above is pretty dodgy. I'll see if we can report the issue upstream. BTW, I tried pinging the bug reporter but email to <a href="mailto:g9352248@trbvm.com">g9352248@trbvm.com</a> bounces.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
