Alright, I was playing assult Ground arcade when I noticed the two images stuck together. Whats happening???

hello?
at the start of the match, the HUD looks fine.

After getting into a helicopter and being shot down or the time runs out, the HUD was stuck together
:(
I bug reported it
This also happened when I spawn into a new vehicle, but by looking at the map it turns back to normal. Is this a special keybind or what???
