Boss bought a Macbook Retina Display and SKO appears funny for him.

If you have the time see if you can edit your graphics card settings in a way to get rid of this bug.
If that is possible I could see what OpenGL option it was and if I can turn it on or off in code.

Otherwise I may send you a few executables to run. Each with different graphics settings and if one works, we can see if it works globally too. They are really finicky and I'm not sure what each option is entirely.

Also I hope upgrading to SDL2 will kill this bug.
