Same happens on my CRS test device… mildly irritating. Did not try ROS 6.6. yet though.
Also, the LCD screen is inverted, compared to the CCRs i have on my desk.
On the CCRs, background color is white, text color is black, while the CRS has black background and white text… wtf?
Ah okay so that was probably just an oversight… yeah I agree that CRS should have white background, maybe you can sneak the configuration for that into one of the next releases.
