Can't stop casting scorching ray

I've got stuck in a state where I'm casting Scorching Ray all the time even through I don't have any buttons held down. It's not consuming any mana and I can't move. If I press the button for it, it starts consuming mana but doesn't spin, except that when I let go of the button I move to where I would have spun to.

I could also recast my golem while this was going on. Desocketing the gem brought things back to normal.
