> There is only one tiny glitch, which is not actually linked to enabling Retina display, I am seeing it also with a non-retina 64-bit build. During and after window resizing, the OpenGL is not redrawn. The OpenGL window becomes bright red, and will stay that way. Any further change in the viewpoint (rotate, translate, scale, etc.) will redraw the content fine, and the new window size is taken into account. So I think it’s just missing a redraw / needredraw somewhere, should be easy to fix.

I tried sticking “_needRedraw = 1” in FltkOpenGLDisplayDevice::reshape(), but that doesn’t work. Will need advice on this, I’m afraid.
