The difference between the Wine output with each driver appears to be that Broadwell/Mesa generates log lines like these:
err:d3d:wined3d_debug_callback 0xed9a20: "GL_INVALID_OPERATION in unsupported function called (unsupported extension or deprecated function?)".
Could you find out what function that is? If there are no hints in the log, the easiest way to find that out may be to put a breakpoint on wined3d_debug_callback() and get a backtrace when it triggers.
