Gesture bar on touch bar filled with white background and off center

Describe the bug
When holding two or more fingers on the touchbar to show the bar for gestures, the bar has a white background and is off center. I'm not sure if there's a setting or not to change this, but I'm not aware of one as far as I know.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
Touch bar

Please let me know if this is a broken setting somewhere, I'm not fully sure if this is a bug or a misconfiguration.
