The ops field should contain a legitimate pointer on return from CreateScratchGC, but you must check the serial number of the GC vs the Drawable - when they don't match, call ValidateGC to set ops correctly for any rendering. Otherwise you'll end up using the wrong rendering functions. Check out other uses of CreateScratchGC (the screen saver code and much of the mi code are good examples).
