Hello, this is a problem that can also be seen on PC, but I am uncertain about Xbox. Occasionally when doing services the Task bar HUD (Top left corner) can become very Translucent, and it can be hard to read, I've posted a Screenshot below. I'm not sure what can cause it, and it happens across a few routes, and probably occasionally on the others. I do notice that when the task bar appears after an objective is completed, it fades in and slides out. Maybe it is just a glitch stopping it going becoming it's normal translucentness?
I’ve experienced this quite a few times over the past few months, it only happens a few times and hopefully shouldn’t affect your gameplay. I believe it does go back to normal when you get the next objective
