Description
I'm porting an X11 application to OS X and there's a section of code that uses XGetImage() to get the color of the pixel below the mouse cursor (i.e. XGetImage(dpy,d,x,y,1,1,...) ). This works as expected unless the cursor happens to be over a GL window in which case it simply returns the X window background color.
