Can you be a bit more explicit about the system configuration and how you got into this state?

This is with an auto-hide panel at the top? Was it visible when the tooltip popup opened? What exactly were the actions you did?

The auto-hide panel in on the left, size 50.
I don't know how to reproduce, it happens about once a week.

Let us know when you figure it out! Until then, this isn't a bug report, but rather an observation.

Thanks!

I'm assumming it's a frame-perfect thing, so unfortunately I'll never be able to record it.
