OK, thanks Bignew.
In the meantime, I have created a temporary solution for pilots who want to mod their planes. You can find attached my version of the MDG_strokesDefs.lua file. In the file I am calculating the stoke_fuzinezz parameter of the HUD elements based on the CENTER viewport aspect ratio:
[cat]
local v = find_viewport("GU_MAIN_VIEWPORT", "CENTER")
local a = v.width / v.height;
-- HUD parameters
-- Fuzziness depends on main viewport aspect ratio
stroke_thickness = 0.8
stroke_fuzziness = 1 / ( 0.8 * a + 1 )
[cat]
Additionally, in the file, you can see the new value of DMC_outline_fuzziness, which makes elements on the AMPCD visible a little better when the map view mode is On.
You can install this modification by replacing MDG_strokesDefs.lua in the DCS installation directory. The file is located here:
\Mods\aircraft\FA-18C\Cockpit\Scripts\Multipurpose_Display_Group\Common\indicator\MDG_strokesDefs.lua
MDG_strokesDefs.lua
Additionally, I am attaching the Open Mod Manager package, for easy installation.
