"Moving image of a garden in a minecraft world"?
In other words: The main menu panorama.
This might be caused by Minecraft not resizing the viewport properly.
Try resizing the window(you can return it back to the size you want once it works),
or using Alt-Enter twice to go into fullscreen and back.
Should that fail,try running unmodded minecraft as a test.
Should that fail,try Technic on another computer.
Should that fail,try running unmodded minecraft on said other computer.
Should that fail,I have no idea. It's their modpack,so ask them.
