as for the Shkval bleeding into the HUD:
open the mainpanel_init.lua
illumination_from_shkval =
{
lighttype = "omni",
position = {0.5,-0.45,0},
attenuation = {0,1,1,0.1},
}
either try these values (i think they fixed it for me, did not touch the Ka50 in ages)
it does not get rid of it completely but at least the light is at a better spot and a little less bright
