Firstly, I'm running the latest build, just to get that out of the way.
This is the first time I've noticed this, it was fine when playing yesterday, but in this game, the display for showing how captured a flag is is broken. Instead of being small and in the corner, its being stretched along the whole top of the screen. Not at all useful. Also, it doesn't actually show any movement, go near any flag and it shows as pictured, like its captured for the light team.

EDIT: Just noticed, if you look over the minimap, the capture bar is appearing there instead, and it moves as normal. But obviously, its not much help.
