--- Comment #4 from Jeff Zaroyko jeffz@jeffz.name --- Tested with wine-1.9.3-217-g0f8a0fd on OS X El Capitan, and the version of snes9x in the download field.
OpenGL renderer string: Intel Iris Pro OpenGL Engine OpenGL version string: 2.1 INTEL-10.12.13
Tested both Direct3D and DirectDraw modes - can't reproduce the issue. Looks fixed.
