Ouh, it's an Access Violation? Then I'll have to try it myself ASAP. Can you try does compiling with -dCASTLE_WINDOW_XLIB helps? Also, what is the version of GTK 2 on Linux Mint 16 Cinnamon?

There is no ready class for this, but you should be able to easily do it yourself Use TGLImage.Draw method that takes parameters ImageX, ImageY, ImageWidth, ImageHeight --- saying which part of the image to draw. You can wrap it in your own class to render a specific animation frame.
