I have grids disabled on all my bars so I don't see blank buttons, however, in the latest release the grid just shows up at some point. Notably, it's happened twice while I was logging out of my toon during the 20 second timer, once with 7s left, once with 3s left. No error is showing up so I can't provide any reference as to why it's happening.

The grid also shows up when I first log into the toon which it shouldn't, going into and out of config mode gets rid of it temporarily until it comes back as above.

I'm having the same issue, except my grid is always on despite having grid unchecked.

Seems okay now.
