I know this is a very old post, but I'm having the same problem, it's
also the problem as described here:

It basically happens whenever I type a space in a textbox when running
my Ubuntu. Also, if
LonelyDragon, you're a genius, it's working now! I just disabled spell
checker and now it's all good. Thank you for your suggestion, and it
completely makes sense, as spell checker would only be activated when a
space is typed. Thanks for your speedy reply!
