I'm typing on my Retina MacBook Pro, and the response rate on the keyboard is terrible. It's like typing on an LCII that is trying to run Mac OS X. As I type, the computer seems to be thinking ridiculously hard about what it is doing. Periodically, these silly character suggestions will appear next to the cursor:
The response rate is so bad that I am literally typing this message one painstaking character at a time, and waiting for it to appear on the screen before typing the next. I estimate < 20 WPM. Keys are randomly repeating as well.
Any idea what this is or why it is happening? This is the second time I've had this issue. I haven't been able to find any info in the Apple forums about it, I'm guessing because I don't know what this phenomenon is called.
