What I managed to find out is that this issue arises due to my crosshair settings
citadel_crosshair_pip_gap -5;
citadel_crosshair_pip_width 2;
citadel_crosshair_pip_height 3.333333;
citadel_crosshair_pip_opacity 1;
citadel_crosshair_pip_border false;
citadel_crosshair_dot_opacity 1;
citadel_crosshair_dot_outline_opacity 1;
Specifically because of citadel_crosshair_pip_gap -5
If you move the crosshair adjustment slider in the settings menu, the error disappears, and you can return citadel_crosshair_pip_gap -5
back through the console.
