My friend just bought the game and is having a weird issue where no unit or structure names are displaying in the commander/fabber build menu. Normally they should show up at the top of the trapezoidal overlay when you hover on an icon. He gets the descriptions but not the main label. I have never had this problem that I can recall. He is on Windows 7 with an nvidia GTX 760.
This bug crept up again today during multiplayer. Everyone experienced this bug except for the host of the game. I've attached a picture to show how the unit labels are missing.
I have seen this one as well. I memorized where everything was on the build bar before it showed up so it hasn't really been an issue for me, but I can see it being really annoying for communicating to new players. "Build spinners!" "What is that?" "the AA vehicle!" Proceeds to read all the descriptions to figure out which is the AA vehicle.
