Missing MCU Button Text - A "Stealthy" Bug?

I ran across this the other day in my Model X and thought it was interesting enough to share (Late 2017 75D, MCU1? [the one before the current latest version I believe], Release 2019.12.1). Many of the buttons were failing to render the text label properly throughout nearly every menu. I didn't notice until I was a few minutes into my drive and it stayed this way for the whole hour until I parked and restarted the MCU (I didn't want to disrupt my music for the roughly two minutes it takes during my drive...:rolleyes:). The Driving, Vehicle, Trips, Navigation, and Software pages were unaffected. My Software page appears to have a completed download that's been stuck there for days, even after the reboot. I haven't looked around to see if that's normal or if that's also another eccentricity.

Everything worked fine and was responsive, the buttons were just missing their labels. Although, this could be part of a new sentry mode feature to help thwart thieves with obscure buttons! ;)
