• The up and down arrow is hidden and red with missing texture when mouseovering.
• The number that indicates which row of action bar you're currently on is completely missing, even while mouseovering.

Edit: Actually there is third visual bugs. There should also be the latence bar showing right next to the row number.

Nothing obvious is jumping out at me on this one - need advice.
