ZSU-37-2 Radar bug

The radar on the ZSU-37-2 twitches up and down when I’m using fixed radar mode. It’s only a visual bug but I find the twitching kind of disruptive on my screen.
Steps to recreate:

  1. Test drive the ZSU-37-2
  2. Make sure you have a keybind for Ground vehicles > Change Radar/IRST search mode
  3. Set the search mode to fixed so that the radar stays put looking straight
  4. Look up and down and you will see the radar twitch
    I have an idea for the fix, make the radar look up and down based on your cursor location.
