I have the same problem too. When working on OpenGL demo in C I noticed SDL2 does output the same ugly pixels by default, yet should support Retina screens (https://wiki.libsdl.org/SDL_CreateWindow - did not try, switched to GLFW which supports Retina out of the box).
Is Pharo window created with native calls or SDL2?
