Fair enough. Then most likely it comes down to the same old issues with hardware accelerationj. Check your settings, update your graphics driver.

Rotobrush does not work on still images and is nort meant to do so. I suggest you actually reasd the online help on how to efficiently and correctly use the tool. For an image like yours one would simply use channel operations based on luminance to create mattes, anyway. It's much cleaner and faster. Have a look at effects like Shift Channels or Channel Combiner.
